Gambling does not choose anyone, theirs is that once you deposit money or deposit into their casino you can play any games that are on their platform.
Now, is gambling for everyone? The answer is clear, and we can see that.
No one chooses to gamble, but everyone becomes addicted after coming here. At first, it is seen that after betting on a few matches, they try to bet more, and then if they lose, they keep betting to recover the loss. Those who continue like this eventually become addicted and cannot get out of it. You said one thing here: is gambling for everyone? The answer is clear. Yes, you are right. Indeed, gambling is not for everyone, it is okay for those who understand and gamble for fun. Not everyone will like it, that is natural. Gambling is for those who have time and want to bet.
Still trying to understand your point though. But we literally make up our mind to gamble. The casinos only make their promotions and it's your personal decision to signup on their platform and begin to gamble. Addiction is just the end point of gambling and when you don't not control yourself as a gambler you literally end up becoming addicted, which might ruin you completely. Addiction grows gradually from over gambling and being too emotional. Most addicted gamblers become so because they fail to see that gambling was meant to be for fun and too it as a source of income which is wrong.
