Gambling can be an enjoyable recreational activity if done responsibly for entertainment, but it is not a wise choice as a primary income source.
I'm agreeing with this. The moment to put in your bet or your capital in a position that you think of would win, you already lost that money. Because you already handed it out for risk. Unless you withdraw it as a win and reflecting in bank account then it's already true. What I mean is that you lose in this game in order to win. So how can you expect this as a primary source of income if you are also constantly losing your money. In gambling it is very random and much more like a game of luck. In fact 95% percent of the participants lose and only 5% wins.
If we talk about big wins, it is quite possible that you are right, but if we talk about small wins, they happen much more often. Only most gamblers miss the chance to take the money because of their greed and continue to gamble until their account is empty.
If we say that gambling can become a means of permanent income, I basically agree with this partly. The probability that any of us can reach such a level is negligible, but I knew two gamblers who lived on the money earned from gambling.
