It makes you wonder, what if you had given him that fiverr, why did he need that fiverr? maybe he had some drug problems and needed his fix, maybe he had huge debts and no one wanted to give him money, maybe he didn't throw himself to the front of the train, maybe someone pushed him!
They did forensics later that revealed to foul play. This is what we heard anyways. But I think you're right in terms of his probable mounting debts, seeing as he was a plain gambler through and through...
