Number of games played, by itself, is a terrible practice metric for chess. Study time is vital, and the type of game is also extremely important. How the player plays the game is important. Do they just play the same opening every time? If so, they aren't going to learn as much as someone who never plays the same thing twice. Do they review the game? The amount of practice value squeezed out of a single game of chess is vastly different between me and a professional, and in turn vastly different from someone who doesn't care at all about chess and me. You can play 10000 games of chess and not learn a thing if you aren't setting out to learn.
