The difference can be shown by a simple experiment. Answer the following question: can you read English(1)? Do you know you can read or do you just think you can read English? I'm pretty confident you'd say you know how to read. If I give you a text in English, you don't even have to think about whether or not it's possible for you to read it, you just start reading.
All Morpheus is pointing out is that when you know how to do something, you don't need to think about it at all, you can often just do it without conscious thought. In a way, he's pointing out that Neo is stuck in the Centipede's Dilemma; thinking about whether or not it's possible to do something means allowing for the possibility he can't, so he's trapping himself by thinking about it too much.
Not sure if this question is on-topic.
It's really about semantics; what that sentence is meant to represent. And that sentence is similar to other lines in films that seem to mean something but in fact are meaningless.
What does it mean in The Matrix universe, specifically? i.e. What was it meant to suggest?
Well in English, if we "think" something is true, it implies we don't know for sure. "I think it's true" is inherently an unsure statement. In the Matrix, you have to be 100% sure of yourself and your abilities, you must know it's true; there must be no doubt. I don't think Neo achieves this state of "knowing" he is The One until the end of the first movie.
When you think about it, it makes sense that it's so black and white; either you've reached this state of realization (like an epiphany), or not. If you're not sure (You "think" you have) then you haven't. It's a binary state, which fits the Matrix as a digital environment. Revelations is a strong theme throughout The Matrix movies.
I’m trying to free your mind, Neo. But I can only show you the door. You’re the one that has to walk through it. You have to let it all go. Fear, doubt, and disbelief. Free your Mind.
-Morpheus
Rather than take this statement alone, take it from within the context of the full scene.
Morpheus explains first, the program has rules, like gravity. Then he explains that some of those rules can be bent, and others, broken.
The pair fight. Morpheus admires Neo's ability, but says
your weakness... is not your technique.
They reengage, and we see some more impressive moves. It ends when Neo does a run up a support, backflips over Morpheus, and then gets kicked into another support. He collapses.
"How did I beat you?" Morpheus asks.
"You're too fast." says Neo, breathing hard.
"Do you believe that my being stronger... or faster... has anything to do with my muscles... in this place?" asks Morpheus.
Neo looks up at him. Morpheus leans in, and gives one of my favorite lines.
"You think that's air you're breathing?" Morpheus asks.
Then they engage again. Suddenly, Neo's neurokinetics are "way above normal," and Mouse is amazed. But still, not fast enough. So, Morpheus then says the following to Neo:
"What are you waiting for? You're faster than this. Don't think you are, know you are."
And, a bit later:
"Come on! Stop trying to hit me and hit me!"
Suddenly, we see Neo's blows blur, we see several... afterimages? of his fists, and he drives Morpheus back, and back, ending with his fist, stopped an inch form Morpheus' face.
Throughout the scene, Morpheus doesn't really teach, or explain. He does. And in doing, demonstrates the impossible is possible here. Neo picks up on this, and does the impossible. Of course, only a little. His journey's only just begun.
The question of the meaning of "know" and "think" comes back in the second part of The Matrix trilogy ("The Matrix Reloaded"), during Neo, Morpheus, Trinity and Merovingio's discussion in the restaurant. The case of which Merovingio spoke, touched another place of live, but the principle is the same. "Know" is the same as being convinced, certain, persuaded, being sure. As long as "think" is near to hesitation, doubt, uncertainty, weakness.
If you "think" in contrast to "know", you can use only some unknown level of your potential. To move the things on or up, you need the access to and get your full power. If you "think" instead of "know", you doubt and you don't mobilise all intellectual and physical resources that you have. If you "know" (fully convinced) who you are in terms of ability, or how the things work, whole your potential can by used.
The matrix isn't the real world, and the laws of physics don't REALLY apply. the only reason they appear to is that the matrix is shaped by the consciousness of the people inside of it, they believe that they are bounded by the laws of reality, and so they are. if Neo can understand that he is in a simulation, and therefore can do much more than typically possible, then he can, but only if he truly believes it, as we see at the end of the first movie.
Knowing is a state of being and is thus immediate. It is a direct connection between the mind and the world.
Thinking is an act and thus takes time. It is an indirect connection, mediated through the self-reflective layer of consciousness and ego.
