Yeah that's a good point. The randomness is introduced by the opposing player and is not intrinsic to the game itself.
As opposed to Sudoku or something where there's only a single player and thus no room for randomness to be introduced at all or games where's it's intrinsic (poker, backgammon, etc.)
