Yes, poker and blackjack are rare exceptions where the mathematical advantage can shift in your favor. In club poker, players compete against each other, not the house, so professionals earn money through mathematical superiority, reading opponents, and controlling their emotions. In blackjack, using basic strategy and card counting systems (such as Plus-Minus), a player can gain an edge over the dealer of around 0.5-1.5%, turning the game's mathematics to their advantage.
