The web has millions of grandmaster chess games and probably billions of chess games overall. So I wouldn't be surprised if it has like 0.01% to chess games since there are so many, if so that would mean it has 10-30 million parameters to play chess with, for comparison stockfish has 10 million parameters to its chess engine.
