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.
This is simply greed and it ruins faster than fear itself. Greed is part of the emotional issues faced by gamblers and the earlier they overcome it, the better for them. The best part about gambling is for the gambler to be stable psychologically and void of anything like greed, fear, anxieties and the rest so that the gambler can truly do what he plans to do and not be forced by the emotion in him. This goes a long way in preparing for what you want to do in the gambling house or on the platform, you should know how many times you want to gamble at that time, the amount you want to use, the time to spend and all that. This helps gamblers to be responsible, accountable and well-calculative in their gambling activities.
But the moment they miss out on these, things turn absurd and they can lose control and start gambling anyhow. However, if a gambler has sensed any iota of deviation from their gambling style, budget or plan, it is better to take a break immediately. Winning once and wanting to win more and more is a very bad attitude of any gambler unless they keep winning and not losing at all. But in most cases, the winning turns to losses and they go home empty eventually. The same thing goes for the losers, they would want to revenge it which is not a good style of gambling. They will only turn you into an irresponsible gambler whose behaviour is similar to that of an addict.
