A correct statement of course we should not gamble when bankrupt even the rich can go bankrupt if they gamble without being able to control themselves, even though there is a chance to win but do not expect it to happen for sure and will help make things better, gambling is not a solution when we are bankrupt because the victory is uncertain.
What is needed when we are bankrupt is a way out and the way out is with our own efforts but not by gambling, moreover there are still many other things that can be done to make money than gambling, when you have enough income and money at that time gambling is not a problem to do.
Most people have the interest to go in gambling if they want to recover their money. They thought that they can easily recover in gambling, however, usually it is the opposite of the outcome. Hence, this will give him more suffering.
