Of course, I also think gambling should not be a hobby but an occasional choice when you really need entertainment in your boring free time, on the other hand, I can also agree with what you said that casinos are great at making gamblers addicted, they are really smart in convincing gamblers that they will be able to get a very big win if they stay there for a longer time with various scenarios that can increase the confidence and hope of gamblers.
So what actually makes gamblers persist even though they continue to experience a slump is because they are wrong in responding to what and how gambling really is, which misunderstanding creates new hopes and interests in winning in gambling so that they stay longer, but I believe that in the end regret will always be a certainty.
Of course all casinos will do various ways to develop their casinos including making them believe that they can win easily if they gamble in their casinos, besides that all casinos must advertise about promotions and bonuses whose purpose is none other than to attract them to have an interest in gambling in their casinos, but indirectly casinos can make them addicted but if we discuss this, what makes addiction is the behavior of the players themselves, not the casino.
During my time gambling, I have never clearly seen a casino tempting people to become addicted, promotions and bonuses are just marketing and that is a natural thing, as you said with those who misunderstand will respond to gambling I agree with that.
