In my opinion, when we win, it makes us more confident to be able to get more than we already got, apart from that, when we win, the temptation to continue betting will be there, especially with the initial thought being to seek profit, there will be thoughts that at that time they were lucky so they continued gambling with the winnings they had obtained, but however the risk of losing would not disappear so the casino could make the winnings they got disappear again and not one or two incidents like this have happened in my opinion. This incident happened again because they made the wrong decision.
winning is actually not difficult, it's just our own thoughts and desires that complicate everything. If we gamble and manage to get a win and then withdraw it without thinking, then everything is not complicated. However, when many gamblers win, they complicate things by following their desire for more, but that only makes them experience problems which sometimes makes them even more disappointed.
Maybe someone becomes more confident after winning, but it seems to me that many people, on the contrary, lose faith in luck when they already have something to risk. No wonder such a function as cashout (which is actually very unfair and close to robbery haha) is in great demand.
I understand perfectly well those who continue to play after winnings and raise bets - I do this myself

When you want to win a serious amount, it is obvious that you should not stop at small ones. From the outside it looks irrational, but in fact such behavior is justified.
It is a norm for gamblers like us to have a certain amount in my that we want to win and when we are on our winning streak, we focus more on winning because what we have is not our target but that is wrong because only the game turns against you which it must, you will not understand how you lost it all instead of stopping when you had profit.
I don't blame those gamblers that go for cash out because they don't want to jeopardize with the little profit that have already and that is the important thing since because it is only what you are sure of. The other huge amount that will make you not cash out but love to see the end of your bet is not certain because one of the game might cut the bet and you lose it all.
