I also think its not impossible but it is very close to impossible. There are certain games where you can theoretically keep generating money with skill and experience. But that kind of people are very rare. Some random person will never generate stable amount of income through gambling. Average person has one chance and its like winning huge amount of money at once. Like one hit wonder. Its not good discourage people, I perfectly know this BUT still letteredhub is right with his argument about gambling addiction.
It's very rare because they apply many things to maintain their focus and consistently set their limits so they can stop gambling on time. We as ordinary gamblers, will not be able to follow because we cannot learn what they have learned. And even if possible, we might take a long time to become like them. And if we end up following what they did, we've wasted our time seeing no other opportunities to make money. And we also have to consider what impact it will have on us if we try to become that kind of person because the only possibility we can get is gambling addiction.
Maybe yes, maybe not. because we don't know the facts, even if someone out there is a professional when it comes to gambling. but do not rule out, if what you say it could exist. it's just that, it's hard to imagine getting a consistent income per day, especially if we target profits. and if any, ideally betting on sports or other types of betting that require extensive skills or knowledge. if in the scope of purely luck-based gambling, I think it seems like it is something that is impossible to do. even I would bet, most gamblers who bet on games based purely on luck tend to lose in every betting session.
I also thought, without ruling out the possibility, out there, there are those who are really capable of making a profit from their gambling session. however, as I said at the start. at the very least, that someone is a professional in the field of betting which involves knowledge, insight, skill and experience, we can also refer to football betting. however, even that does not guarantee that at every bet you will always get a win even though it involves insight, study, analysis. after all, luck is always involved in every gamble. but what is certain, gambling is an activity that involves fun but has risks that everyone involved in it must be aware of.
If a person is a gambling professional and can make money from gambling consistently, he will not say it to too many people and will keep it for himself. But being consistent in earning income in gambling every day is very difficult and not many can get it, while others will only experience a lot of losses.
Someone who is a professional has managed to master everything that must be owned to make money at gambling. And as you said, people like that have insight, knowledge, analytical skills, self-control and much more that we don't know. And that is why many people fail to make money from gambling, especially if they have high targets to achieve from gambling.
