The main loss is that their financial situation will become a mess, and once their financial situation becomes a mess, it can have an impact on their family or even their friends. Also, it's not just financial, this can actually be detrimental to other things, such as relationships with each other as well as your own health. When someone becomes addicted to gambling, there is a possibility that they will experience a change in attitude and tend to become more stubborn. and of course this has the opportunity for violent arguments between people addicted to gambling and their families or friends or even other people.
When they become addicted to gambling, it is likely that they will only focus on their desire to gamble, and they may ignore everything around them, including their family, their time will probably only be spent gambling, even though they have run out of money to gamble. However, people who are addicted will look for ways to gamble again, whether by borrowing money or something else.
Then the OP is right. We experience more loss than the wins but most times when we win it covers up for all the Mutiple times we have lost, and we don't get to reminisce about the loss. The truth is it is in our nature as humas to feel regretful when we do something and failed especially when we gamble. There is no gambling that will tell me that he hasn't feel so depressed after he had loss, no matter how he tries to control his emotions there is always this wish that we should have one and it just one game that made the bet loss. We start regretting why we include that game in the bet.
Now if a gambling addict experience this depression everyday his entire life is ruin because there will be no fun and happiness until any day he wins and go for merriment. Which mean it's doing him more harm than good and it's affecting his family or people around him too.
If you gamble frequently, what you will experience more often is defeat, of course there will be no consistent wins. There is also no point in dwelling on defeats that have already occurred. We must be able to let go of the money we bet when it is lost, because it is a sure thing. So it is very important that we can allocate an amount of money that we can afford to lose, so that we don't bet beyond our capabilities, such as by risking a large amount of money but we are not prepared to lose the money we bet. The desire to win certainly exists among all gamblers, but we must be able to see that winning at gambling is not easy to obtain.
Of course, there will definitely be regrets, especially when gambling where the aim of the gambling is to make money, but the end result is that it turns around and results in losing money. That's what we have to accept well, don't assume that gambling can give us easy wins or money. The aim of gambling is probably to make money, but we have to put that aside, because that way we will probably be concerned about losing or losing the money we bet, and continue to encourage us to gamble, unfortunately that will only make things worse. Not only will it be financially detrimental, but other things can also be affected.
