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.
Good point. People (like me as well) are easily confused term "strategy" as i never really thought that even unproductive strategy, that is doomed to fail and based on gambler's fallacy is still considered as a strategy. But i recon that in sports there are more ways to implement different strategies, as you can do ton of research about the players and teams. I am not saying that they work, but they might have better changes working then using it with house edge games. And i would say they can give way higher edge then just playing with low odds.
And obviously those strategies can work in poker. Only proof i need for that is the fact there's often same groups of people ending up in last tables in poker tournaments.
