Doctor Strange seeing the one winning scenario, meant he kept looking into the future for 5 years after the snap where nothing was happening, until a rat presses the button to get Ant-Man out.
Where is the logic in that? The chances of that is way smaller than 1 in 14m.
Also, doing that to see it means he must have done it to other scenarios where nothing is happening at all, no rat and no Ant-Man, so how long did he look into those scenarios where no rat presses the button before he gives up and move on to the next possibility?
