If they have that certain control from their emotions then it's really okay for them to gamble as they will not resort to gambling as source of finances but instead a venue that they can find enjoyment, there are people who are engaging to gambling with high aim to win big, thinking that with that mentality they will manage to win and can continue taking money out from the gambling house.
Just like what you said, gambling for fun and not to exceed will keep you away from getting addicted, gambling irresponsibly though will bring you to a big trouble and it will lead you to addiction.
The main issue on here is that not all people would really be having that kind of discipline when it comes to gambling thing or activity on which instead that they would really be doing things in moderation
but rather they do become that impulsive.
Gambling should really be that for fun and not something that you would really be thinking up well on how you would really be making some money because once you do find yourself
that being desperate on how you would be making yourself getting rich then this is where desperatation would be kicking in and this would really be that in result
into those devastation on which this is something that we dont really like to happen.
gambling is not to make money, that is not the main purpose of gambling, because as you said, gambling must really be for entertainment, and I always emphasize that people who gamble must be able to accept the money they lose in gambling because they lose in gambling. it can't be avoided either. except that avoiding big losses can be done by having good self-control, but it is very rare for people to have good self-control when gambling, many of them gamble without self-control, causing big losses, then no It's strange that many people experience big losses by gambling because it is each individual's fault.
