Aside from money, of course luck is also needed. Another one is discipline, self-control, patience, very good decision-making skills, etc.
While you can make huge amounts of money through gambling, you can get huge losses as well - so huge that it might change your life negatively. I don't know anybody who's living their life through gambling, but I know there are some who are doing it. Gambling can be a source of income, but you need a huge amount before doing it. For me, I don't see it as a source of income, but only a source of entertainment. That would be a better approach with gambling because even if you lose, it's ok as long as you enjoyed playing.
Can anybody share some popular gamblers who are living out their life through gambling? I mean gambling as their main source of income.
The truth is that lucky gamblers can benefit from gambling when they're lucky to win and as the luck of winning in gambling is implied, no winning time is assured that's to say it's not worth it to say it's a source of income and insisting that you must making living out of it will only make you loose the little you've budgeted for it.
But being lucky is not consistent so its hard to rely on something that we are not really sure. Since most likely those people who tend to believe that there's gonna be a big changes in their life will happen especially if they became so luck and win a lot of money might became broke because its rare phenomenon that they could able to win more bigger amount by spending less for it.
So instead of betting their future on gambling just take all easy then bet in moderation since luck will just come if the faith let us win. But if not still fine if people who are in total control will just be happy since they will look at the bright side even if they lose and just say its fine we can shake those losses off since we are still satisfied then also happy with the result.
