Would the number of players at a poker table alter a capable AI/ML's chances of winning?
I don't see how it would, so long as every player was playing fairly.
I would assume that it would not matter if the unknown cards were dealt to more players or still in the deck.
EDIT (to add some context): I am trying to determine if it would be "safer" for human players to play poker on larger online poker tables vs smaller online poker tables. Given that they can never be sure if it's an AI playing behind one of the various screen names they're up against.
