.Ibelieve this works similarly like card-counting, it's not foolproof, because if there's even a minor movement on the market, then I will lose. Still, it gave me better odds of winning.
You understand that casino does not allow card accounting, they will simply show you the exit and if you don't follow they will force you. I don't think this statement helps you to win the case.
Your gain was unrealistic and obviously it was spotted by their radar. If the provider don't accept your winning then I don't think the casino will help you.
