Unless you are talking about poker or a similar game then it is impossible to make money long term in gambling, that is a reality we must accept, those that are looking to make money in gambling will lose more money than they can afford, this is why the common recommendation in the forum is to gamble with moderation.
Poker game is not really easy as well to make money in the long term. Some player are good to play in a poker site but not everyone can make money from a poker site. It is hard and as hard as usual luck based game. I dont think it is profitable even for poker player because many poker player lose than win
I think poker needs practice and it is not like dice or slots where your skills dont matter at all. Poker is an EV+ game after all and thus the players skills are important in order to out-play that opponent. Then in dice you dont need any skills other than being able to roll the dice. If you are thinking of playing poker then make sure to practice it online or offline before you actually play it anywhere in a casino.
Another thing about games of chance like dice is that it doesn't matter what betting strategies you try, you odds of winning don't improve. I've read about several strategies like martingale, etc. and they seem to make since but the math behind it shows that it doesn't work. I've even tried these strategies and have found out first hand that you will eventually lose over time because you will eventually get a long streak of losses and you will run out of money.
