Gambling as a source of income never makes sense anyway, I mean we are talking about something that will statistically and mathematically make you lose money 100% guaranteed. Doesn't matter if you win big, if you keep gambling then you will lose. Source of income suggests you are thinking of it as a job, and that means we are talking about something that will be done for many years, even decades.
So, it doesn't matter if you put up 50 cents and win a million dollars, because if you want to keep going, eventually you will lose that million dollars too, you have to get out to make that money and getting out means that it is not source of income, it would be saying like lottery is a source of your income, it is not, it is just luck for once and that's one in a trillion chance.
Yeah, if anything it would be a one-off that makes you a millionaire. Very different to have a steady pay check every month like you have in a job.
So, I don't really know why people think of gambling as a job, or income making. It could be just a fantasy I guess.
But there are jobs related to gambling that do pay an income, like the influencers that show videos about it, etc. But that's not really gambling, that's more like advertisements.
Now, coming back to what makes some people turn or make gambling their source of income, alot of situations can lead to this, and one of those is lack of real life jobs, or lacking the educational qualifications to secure any good paying job, and also, when a person doesn't have money to start up a business, they can easily turn to gambling as a source of income, hoping they can win enough to atleast, start a business, but the unfortunate thing is that, most end up getting addicted before they win any good amount of money.
