What if you lose? How do you cope up with real life expenses if you have nothing left on your hands?
This is not a wise decision to gamble all in that you have to run your real life.
Just like he said, if he lose, there's no drama. He's emotionally prepared for the all in loss. It might not be wise to do that but imagine if he won, he'll double or even triple his weekly payment. And if you're asking what would he do if he lose, he's either not paying for other expenses like the electricity bill, water bill, food, shelter etc. or he already has allotted some money for those expenses.
