If they realize that they can not earn money easily from gambling, they will start to reduce their gambling activity and time. They will try to understand that gambling is just for fun and not a place to make money. We can't spent money and lost a lot in gambling because we must think what other problem that can arise.
That is what some people will do but some people genuinely thinks that if you just keep going and playing at some point you will win and you can get back you have lost. Which I suppose is correct. If you play for 100 times, at least 1 time you will win. But the question should not be the chances of winning but the amount of money you are losing by continuing. Is playing for 100 times and winning 1 time worth all the money you have already lost? Probably not but that is not how some people think. They just want to win and they will not stop until they do.
The chances are higher that you will only get half of those 100 bets or maybe even lower. This is where tension will happen as you are near depleting your balance. You get mad, you get stressed, and then you start to be blind and tell yourself you might get it back after depositing it one more time. It's where a gambling addict will spark and then he becomes one.
We should avoid this. We know we are dealing with a casino that has a house edge and we must be wise about it. We can play, that is not a problem but let it be a game only where you will enjoy it and not be stressed about the results of the game. We do forget that a lot of times.
