That kind of person thinks he has no choice but to gamble only. The lack of money usually means he doesn't have a job which means his first option should be looking for a job and not gamble.
But then anyway, if he already is addicted to gambling despite having no money then he will not have a big capital to gamble unless he takes a loan from someone which means he'd be in big trouble when he loses that amount.
I have seen that most cases of addiction are caused by a lack of money, there are even people who have a job, but when they fall into addiction they do not continue working, they do not believe in that money but in the money that is earned in a casino, and that becomes almost a religion, then it is difficult because the person closes himself off, and what seems Logical to them does not work but what is done in a casino.
Given these things, it is extremely necessary for each player to know about economics, risk management, in this one must be very clear.
