You do not need to be surprised because some people think like that. They want to make money from gambling, especially because they have often seen several people who have succeeded in making money and making gambling a place to make money and a source of income. But we don't know how much money they have used until they can make a lot of money from gambling. Even so, some people can really make money from gambling, but they have better abilities than other gamblers.
Other gamblers still lose a lot of money from gambling. But that doesn't make them realize that what they are doing is wrong, and instead, they continue what they have been doing. And what happens is that they get deeper into gambling and have difficulty avoiding gambling because they feel they are tied to gambling. But actually, they can still get out of gambling, which requires intention and hard work. We already know that gambling is entertainment, so we do not need to use it as a source of income but only as entertainment.
Just one single win give them that hope, I mean they think like that after experiencing that they are able to make money after winning some bets, not knowing or not expecting that after that winning streak reality will stab them at the back and start emptying their savings, people who believes that they can make a decent amount of money out from gambling most of the time losses a lot.
Yes I understand what you mean, it's basically like that buddy and that's the temptation in gambling, even though they only get one win but strangely just that can make their hopes even higher, assuming that they will be able to get another and bigger win the next time, But the reality is that well as you said after the winning streak there will be a clear losing streak too but the defeat seems endless and only for those who can restrain themselves will survive and will not be too exhausted all the money, so the importance of self-control is none other than when you are in a position like this.
There are many factors that lead them to lose, greed or unable to control, instead of quitting while you are still in green they will choose to push for more and try to win bigger amount of money, from that time, the appetite already rise up and the adrenaline keeps them think that things will be sided to their favor and let them win the desire amount that they wanted to cash out.
Yes, such a mindset is only for those who have entered the trap of addiction who say they can get income from gambling, and obviously the end result is that in fact they actually lose more, but strangely it doesn't seem to matter to them and just keep playing. It is true that of course there are many factors that can make them finally lose, one of which is the greed you mentioned, it is not uncommon for me to find someone who has managed to get a win but finally loses again, and that's because they are too greedy, never satisfied with what they have got and always want more. You have to remember you won't be able to get lucky at all times, so even if you initially win but eventually you lose again it's because of greed, although there may be those who succeed but it is very small in number and chances.
