I think Many gamblers try to hide their emotions while gambling, but not all of them are successful. This is because emotions can play a significant role in gambling, and even the most experienced gambler can struggle to control their emotions during a game.Some gamblers who are able to control their emotions may do so in order to project a certain image or to avoid giving away any tells to their opponents. However, other gamblers may fail to control their emotions due to the adrenaline rush and excitement that gambling can bring.
