Gambling though is a risky game that the chances of winning and losing is in equilibrium but however in other for one to have a possibility of winning, it requires a steady income.
Having a steady and regular income is very important as a gambler because it would enable you to scrap out money you should use for gambling, feeding, taking care of yourself and family and other miscellaneous.
A gambler who has a steady and regular income can have the possibility of winning because his gambling habit can not affect his personal obligations as a man even if he's an addict because being addicted to gambling doesn't actually implies that one will eventually stake all his money on bets but rather someone who plays gambling frequently. By having a steady income, he can take care of other life responsibilities without being affected by his gambling activities and moreover, someone who have a stable income can be aiming to win higher amount in his bets and might be lucky of winning one day and use the money to establish an investment.
Your thoughts on this
You should also add enough income, like you still have spare money to gamble, because right now there are a lot of people who have stable and regular jobs, but their salary is not enough, it is only good for their needs and their promotions are far from true so having a enough salary and not living paycheck to paycheck can make you more likely to gamble even if you lose on that bet because you are not spending money that is supposed to be budgeted to others unless you are addicted, which is another story.
