I'm not sure how Rocky fits the same pattern as The Karate Kid. Even at the very start of the first Rocky, Rocky is a journeyman boxer, who's been in the game a while, and goes to the gym on a... ok, on a semi-regular basis at best. Yes, he's undisciplined and doesn't have an amazing track record, but when he gets picked by Apollo to get a title shot, it's *not* like he's learning to box from scratch. He effectively has a training camp with Mickey to get him in top fighting shape and mix up his form to throw his opponent's research off - but that's how a lot of professional fighters prepare for a fight!

(I mean, it helps that his fighting style is mostly "let the other guy tire himself out by punching you in the face for 10 rounds straight, and then get some decent haymakers in when they can't lift their arms any more" which any fool with an iron chin can try to implement, but even so, the implication is that he starts off with plenty of practice at it.)
