but still i think the math stands up that if the player has a larger bankroll than the house, player has a larger chance to bankrupt the house than the house has to bankrupt the player on a 0% game

It seems kind of obvious that in a 0% edge game whoever has the biggest bankroll has the smaller chance of going bust... Not to say that everything is intuitive with probability stuff, but in this case I think it makes sense.

and this is where i calculated the ruin %.. if you input the odds of the house win as 0.505 and loss at 0.495, at 100x bankroll compared to max bet, the chance of ruin is 14%... which is really high. i wonder how they came up with that formula.

Pretty sure they're assuming the max bet is a constant. Casinos generally don't reduce the max bet as players win...

When the bankroll is crowd-sourced and changes dramatically over time like it does at JD it makes sense to set the maximums dynamically so they change with the bankroll. That has a side-effect of vastly reducing the risk of ruin.
