I don't even think that there is a strategy in gambling games. What strategies can we use in the game to enable us to win? I don't think there is, because gambling is closely related to luck, so I think we will win if we are in a very lucky situation at that time.
In gambling games, betting patterns are called strategies, such as martingale, where you double your bet after each loss and reset it back to the base bet after a win, which means if you are gambling with $1, you make it $2 if you lose one bet and make it $4 if you lose two, and that continues until you manage to win a bet and then you come back to $1 again. There are a lot of patterns such as this but they aren't going to make you win in the long run.
A strategy in a gambling game is a recipe for disaster. People often use such patterns and strategies to cover their losses but they end up losing everything eventually because you never know how big of a loss streak you might encounter when you are gambling, and your bankroll will get exhausted in no time.
