Sorry OP your discussion is a bit confusing because it goes around in circles, for me the point is that gambling is not intended to earn income, this is not a job and the reason is clear because there is no certainty and guarantee of anything to always be able to produce. You can see for yourself that most gamblers who make winning a priority always get the opposite results or I mean lose a lot of money instead of making a profit, for me gambling is nothing more than an activity to fill boring free time, or just for fun.
That’s how it should be, you shouldn't place too much hope on gambling, it's just an activity for entertainment when you have some free time. For it to become a way of earning stable income, first you need to learn how to make most of your bets winning, and then you need to have a rather large bankroll to play safely. But even these two conditions are quite difficult for an average player to fulfill.
