Gambling is not a job and should never be treated as such.
As long as there is still a chance of you losing and not being in control of your predictions it will never be suitable for a career and unlike trading where you can improve your knowledge and skills and eventually helps you perform more trades efficiently gambling is not like that since 90% of it is based on luck.
And rather than waste your time looking for means to make gambling a means to earn passively (which would make some results into using some unethical means to achieve it) I’d advise you look for a skills that can later be monetized that’s far more better than betting on luck.
A job is when someone earns a consistent income. Common gamblers who play using their own funds can't be treated as a worker but it's possible that gambling can provide a career because a casino can hire workers. Also in the pro-gambling scene, there are companies who can hire skilled gamblers, just like in the pro-gaming scene.
Trading on the other hand can be a career if the trader is well-skilled. It can also work the same as I said earlier, where are company can hire a trader to work in a copy trading service or to provide a premium signal. Any skill in any field can be monetized. It's just that some are like you said (unethical). Maybe there are still some people who won't mind doing that, just for the sake of earning money.
It is actually Difficult when you see the game as a job, because it is something very treacherous, it should not be seen as an income because it is the worst decision of all to see the game that way, now when we make the analogy with trading things can be seen in another way, in trading things can go in the direction of what the trader knows best, the more he Speaks the more he will make Money, that is the law, then if a person is not good at it he has to trust what know, and obviously we will follow the best path , then basically when we see that things can be a little less complicated that's where it gets complicated, because when we see that Everything can turn out well we can turn around, in the market for volatility and in the casino, because the casino has many things in its favor, the house advantage, which is something obvious, the other thing can be the very complexity of the game, which makes you lose, all of that makes more and more problems. So you know in this order of ideas we could think that the things that are treated with a caisno must be done with great care.
A successful player for me is one who only plays and wins every day, there is no other way, I couldn't classify anything other than the same and I think many see it that way too, I couldn't say that a player is good and that he is not win , because what you are Going to do is accumulate losses which turns into loss of money, something that should never be allowed. We have to give our money the importance it requires, there should be nothing else that doesn't Matter more to you than our money. Without money we couldn't do Anything , in fact when the money runs out everything goes away and how are we left? wrong , because we Simply cannot make more Money , then our Money , and being in a casino seeing it as Income is not good, it is wrong, and it is not good that other players Think that this is the best Option to see the Games of Chance.
