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.
Gambling is not fun at all. How are you going to feel playing bets always and not getting rewarded at all. It is very painful when we pain on a particular game ans waited for the all the games to end up in winning but one particular games which is supposed to be the last one that supposed to bring the entire profit have to become the black sheep that scattered the entire bets. This is a painful scenario and I have noticed this many times which most time used to make me think that the last game of a particular bet is always dangerous especially when you have been given cashout for you to take partial profits but you still decided to ignored until everything ended in loses.
