This can happen to people who are not satisfied with what they have got, because those who are not satisfied with the winnings they have won will deposit money again and perhaps with a larger amount because they feel it will be easy to get the winnings again. so they bet again with a large amount. and if they can't control themselves, maybe they will do this continuously without realizing the risk of losing a large amount of their money.
and the wins they get make them believe they can win again if they gamble again, but what they should realize is that the wins they get are based on luck, and luck certainly won't last long with us, that's what we have to pay attention to. that's clear, especially when they get a win they can think it's a chance they can get a bigger win by exceeding the win they've already got, of course to get a bigger win they will increase the amount of their bet to get a win, and the possibility is in the next round they will only experience defeat which will make them lose self-control and make everything chaotic.
Your opinion is absolutely correct, that someone who is not satisfied with what he has obtained will try to pursue it again until his desires are truly achieved and in accordance with his expectations. It's like in gambling, if someone has won, he will not necessarily be satisfied with just one or two wins, maybe he will chase it until he is tired and feels satisfied. Then slowly he will experience defeat and that is the result if he is greedy in gambling. Instead of making a profit, he will experience a lot of losses there and that's what actually happens in gambling, it's just luck for the person who gets it.
