Yes, I agree with you that the point is not to take gambling seriously or do not prioritize gambling because it is nothing more than a game of probability that runs full of uncertainty, which usually in some cases most people are even dominated by regret and disappointment when always trying to make gambling as an income. And what we have to pay attention to here is the possibility of losing or the risk because in gambling usually the risk will be much greater than the chances of winning. Especially if you or whoever it is trying to make gambling a job to find the main income then most likely instead of earning but most likely you will actually experience a lot of losses. You already said one of the reasons is because gambling is a business for casinos that will benefit themselves by taking advantage of gamblers who have a wrong understanding or take advantage of those who always overdo it, so we always recommend seeing gambling as an entertainment game.
If it is a fact, what happens is that the game should be seen as entertainment as something that should be available so that you can have a different time, we cannot say that it is only for enjoyment or only pleasure, the goal is to make money, but In the event that it is not fulfilled then we still have to accept it, when we start inventing to try to earn more money we can take many risks, among those risks is that of losing much more money, so these are the things that we must see, first, see how much money we are willing to spend in the casino, for me that is a priority before playing, second, if we do everything possible to win and it is not achieved, we have to assume that it was lost and another day we have to keep trying, but seeing it as income cannot happen because it is simply irresponsible thinking.
You have said that if we want to get a bigger win then the level of risk that we have to take must also be high and you have also said the right thing that most likely a gambler will only experience a greater amount of loss, so this is the reason why gambling should not be used as a place to earn, or that means don't put hopes on winning because overall when you take more risks or gamble too often then most likely these actions will only make you experience a greater amount of loss than getting a win.
Actually if we think using common sense then of course the better choice is not to make gambling as anything even if for example you come with the intention of having fun because it is still ultimately like the idea of losing your money intentionally, and if there are other activities that can also be fun without the risk of losing money then why don't you choose it? This is suspicious, but yes, everyone has their own choices and maybe I would just suggest that when you make gambling a pleasure activity for example then you must really apply caution and high vigilance because it is very possible that at some point you experience a change in mindset that leads to impulsive gambling due to not being able to resist all the temptations that look tempting which in the end turns out to be the result that does not match the expectations that make you emotional and make decisions that lead to impulsive gambling. On the other hand you have a pretty good prioritization where you prepare yourself for the possibility of losing before you start gambling, and this is a smart idea to strengthen self-acceptance when it turns out that we lose so as not to get too emotional.
