It all depends on the gambler involved in this kind of situation, making gambling as a source of income isn't bad at all as long as the gambler can always sought a means out for himself everytime
For people not to make gambling as a source of income is like a means of telling people how risky gambling is. I do tell people that they should not rely on gambling at all, that they should even be very careful about it. Not only gambling, but also trading. These two things are very risky, they can turn a rich person to a poor person in just few hours to days. People need to be careful.
Someone can decide to take just 5% of his weekly income to gamble weekly, that is not be. I do advice people not to use more than 5% of their weekly income to gamble weekly. But that do not stop me from saying that people should not make gambling as a source of income because I always think it is good for people to know that, which is actually the truth. Gambling should just be for fun and nothing else.
Indeed, gambling cannot be seen as a source of income, I know many friends who have told me that before playing in a casino, they told me that they see the casino as an ATM and that is a blunder, when they played Sometimes they won somehow and they told me, but I really didn't tell them anything, I just told them that I was happy but to be very careful, and after a while, at least 6 months later, I would see them again and they would tell me that They had left the casino because they lost a lot of money, that this is a vice, that they lent money and that they are still paying it off, the good thing is that they are working normally and paying their debts.
for sure, a lot of gamblers at one point went to the path of borrowing money as they wanted to fulfill their desires. and this is why gambling has bad connotation because of gamblers who are in deep debt but still trying to make a loan thinking that they can win and pay off their debts. however, very rare that it happens, the usual scenario is that they will incur more debts after debts.
