In theory, gambling at a casino is completely dependent on luck. In practice, education or skill can give some people an advantage at specific games, while alcohol or confusion could hurt their chances of winning. 

Slot machines are almost entirely luck-based, but other games depend on the ability of the players. Card games like poker and blackjack are common games that people might play with the hope of winning big or tricking the casino. 

If management at a casino has formally asked you to stop playing a certain game, can they enforce that rule? 

Casinos are private businesses with their own rights

Although you as a consumer have certain rights, you do not necessarily have the right to demand specific services from any particular company. Casinos, like any private business, can choose to ban people from their premises for violating the rules. 

In fact, they can even impose restrictions on when people can enter their premises or when they can patronize the business. Limiting someone to specific games or preventing them from playing blackjack if they have a history of overtly counting cards is a way for a casino to allow a customer to continue visiting despite previous questionable practices. 

If people try to go to a casino to gamble after being barred or violate restrictions a casino places on their time there, they could face additional repercussions, possibly including criminal charges. Fraud, theft or even trespassing charges are possible.
