Wait, I don't get it. How do I get the coins so that I can gamble so that I can mine coins? 
The initial distribution proccess will be announced soon keep an eye out.
Think of it like this a bank has 50M in stock so it allows 100 customers a loan of 500k so even if all customers come at once to withdraw their money the bank will be at 0 but not be in the red.
So, the maximal bet size will be lowered so that all winnings could be paid even in the worst case at all times?
Maybe it could work, if the bank would be big enough ....
That is not entirely how it works Proof Of Risk is a new protocol implemented in the first internal decentralized currency to make sure things are able to run smoothly independently. Your comment isn't entirely true but it catches the gist of it. The technical details of POR (Proof Of Risk) will be released with the source code at a certain stage in our development.

Side note: if banks worked like that, we probably wouldn't have Bitcoins around
Read my entire example that was entirely my point
