This is a recent story, probably from the 2000s.
The protagonist of the story is a teen-aged boy whose highest "rating" (based on the entirety of the world population) is in... magic, or card tricks, or something to do with cards? He laments he will never really be good enough to be famous/popular and have a shot at being in the Top 100, etc. Eventually he meets a girl who is disconnected from the "system," and when he shows her his card tricks, she is impressed because she has never seen anyone do it better, since she isn't a part of the "system."
There was a part in the story talking about how one kid who had never had sex before, had sex with someone else and instantly became the #1 rated "male intercourse with female" in the world, and how everyone was waiting for him to have sex again to see if his rating would stay high or plummet out.
I don't remember if the story was CCTV-style constant surveillance or 'eye cam' or both. I do remember that the protagonist and the girl had to go somewhere secluded (and take out their contact-cam?) to get away from being recorded.
