That's a pretty bad definition of a AAA game. I'd say it's a game that is up to the current standard in video gaming, which is rapidly evolving. This means that the graphics aren't archaic, the game content has appropriate magnitude (the game doesn't feel short, or lacking in items, game levels/areas etc. as applicable for each genre). It's the level of "polish" the game has. Now that implies the team sizes and budgets, but not that the game will be a bestseller. It can be a total flop, although the high cost of producing such game implies that it has significant marketing, which should bring at least some sales.
