Seems like an underground gambling den gone wrong?

It shows how risky such events are to organise for the organisers are always looking to make money from the game and they will try to include things that are beyond their control. Usually this leads to problem and sometimes the outcomes are in blood.

But I dont see how relevant this is to gambling. More of an organized crime.
I see the comments and understood it better now. Pretty complicated to give a one line answer as cause and effect.
