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
All gamblers have an equal chance whether they have a steady income or not, you're having a steady income is not your ticket for a chance to win more than those who have no regular income.
The big advantage of having a regular income for a gambler is they can play without the pressure of needing to win because they can sustain their bankroll compared to players with no regular income they have to protect their bankroll or find ways so they can gamble, usually, they take a loan from friends and banks, use their savings and sell their kinds of stuff like cellphone, so they can continue gambling.
