I think casinos often use advanced tactics to prevent gamblers from using winning strategies. For example, if they notice that a particular player is winning frequently, they may ask the player to leave or restrict their access to certain games or change the game's rules. Casinos also frequently use surveillance and security to prevent cheating and monitor suspicious behavior. Some casinos even employ computer algorithms to track players' behavior and detect patterns that may suggest advantage play. Overall, casinos do their best to maintain their advantage over gamblers and maximize their profits.
