Every bingo card is generated independently at random, and everyone in a game sees the exact same sequence of drawn numbers - no card has any inherent advantage over another. Players can buy multiple cards (1, 5, or 10 at a time, up to 18 per game), so a game's real unit of competition is the card, not the player.
Only cards belonging to a logged-in player are eligible to actually win - an anonymous card can complete a line, but it doesn't end the game or count as an official win (see the game page for why). By symmetry, if there are M eligible cards in a game, each individual eligible card is equally likely to be the first to complete a line: 1 / M. If you hold k of those M cards, your overall odds of winning are k / M.
(Presence of anonymous cards doesn't change this - their random finishing order relative to the eligible cards is independent, so it doesn't shift the odds among eligible cards. In the rare case two eligible cards would complete on the exact same draw, the pot splits evenly between them instead of one taking it all.)
