In my opinion , a gambler should never rely on his winnings to be his income! If you do this , you really have life issues that should be properly address because it's not healthy at all and what will you do when you get a losing streak ? because let's be honest here , it happened to all of us.
On the other side , if I go to my local bookie here I will see 2 or 3 familiar faces that are from morning until midnight there and guess what guys ...their monthly income is based on gambling from morning until night but you can't imagine how stressed it is to actually think and re-think strategies just for 1 bet.

Usually an unemployed person will prioritize the results of gambling as a steady income and sometimes they also expect the winnings to be able to eat tomorrow or use the winnings to have fun gambling again, unfortunately I am a worker so I only play gambling on weekends, even if there is a match football, which I usually often bet on sports betting while playing games at the casino as long as the event starts to fill the time.
I never thought of making gambling as a steady income because it would obviously stress me out and think it's unhealthy to be frivolous trying as much as possible to find victory and achieve targets, even though we know that gambling doesn't always give wins, usually every day it always ends in defeat.
Cannot really blame them if that's what they see because whether we like or not, gambling is truly the shortest way to have some money and it is also the fastest way to lose it, so it's a gamble to make and people are still going to take the risks even after knowing the fact, just like you said, most are the unemployed person. Unfortunately, while their reason is somehow correct as they are just trying to survive, they are finding the money in the wrong place.
Indeed a wrong place on which instead on making money, they would eventually lose even more which is something that a very common scenario to happen into those people who do believe that gambling is
really that something reliable when it comes on making money or income which it is really that totally opposite. We know that there are still people who are really that having that kind of perspective on which
they do really believe on something that they do have in mind on which they would really be pushing it out for it to happen and make it real and this what makes that desperation would kicked in,
Until they would be able to realize that things turns out to be false and having those regrets but its already that late.
Making gambling as an income is really just that possible through those people who are really that expert or being professional on some card games and sports betting.
Yes, its possible but its not something attainable by someone.
