Talking about professional gamblers. It is already a person who knows their responsibility and risk. They become professionals because they can handle themselves more than others. So I would say there is no issue with them and nothing to worry about with these people because they know what the right thing to do is. We just assume the wrong thing.
That is why I have big respect for these so-called professional gamblers. There are few because only a few gamblers do right. Of course, they are rich gamblers who are not afraid to lose money.
I think so. Those who can control themselves well, in my opinion, are considered professional gamblers. In my opinion, being professional doesn't mean they win every time they gamble; in other words, they make gambling their own source of income. Furthermore, I think those who can control themselves are winners at gambling because knowing when to stop is, in my opinion, a key to success.
And basically, if we want to gamble, we must be prepared to lose money. In other words, we must not be afraid of losing money, as you said. This is mature behavior in gambling.
