I think more precisely gambling is nothing more than a choice, in the sense that everyone is free to choose whether they want to get involved or not at all, and of course as you said that the casino does not guarantee that every gambler will be able to win, there is no guarantee and certainty in an activity that is probabilistic, so this is why before you decide to get involved you must first consider, especially asking yourself whether or not you are ready to bear all the consequences of the risk.
On the other side of the story that you have told regarding your experience in gambling, then maybe I would say that what should be sought in gambling is not a big win but it is about how smart you are in controlling everything well so that you stay in the safe zone.
Yes, you are right that gambling is a choice, it depends on whether we want to get involved in it or not at all. But of course casinos will also try to attract more users, one of which is through advertising or promotions that they do. They are willing and able to spend a lot of money just to pay influencers or create promotional ads that will make people interested.
It should be underlined that casinos are also doing business here, so their goal in creating a gambling platform is to make a profit. So just by looking at that, we should be able to realize that gambling cannot make us get a steady income and make it more of a means for our entertainment. It will be a problem if we think gambling can be used as a place to get a steady income.
