That is actually what I ever experienced, losing more, and gaining less in gambling. That is why I quit gambling. Because until now, I am still confused about how to be in the gambling well. I tried to learn about the strategy of betting and the game that I participated in. But I fact, I still lost more. I feel so dumb 
Gambling is used as a place for fun and if you put all the money you have in the hope that you can get a lot of profit then it won't be possible because no one guarantees a win at every gamble you bet on so maybe you should be able to change your mindset. when gambling and use money that is not being used because the risk is that money at gambling can be lost instantly when you lose.
