Yea it also depends on what the court accept but is this not depending on the region where the casino is registered?
There are schemes which they may be able to pull off under some regions which will be favorable to them and in other regions not going to go pretty well in their favor. Some go for every means to earn not just profit finding loophole and other means to get customers money acting shady/scamming to them.
That's why if you live in a jurisdiction with crappy law enforcement, it's a complete mistake to play on a shady platform that has stupid malicious ToS in the first place, forget the ToS, even your absolute rights will be thrown in the garbage bin, so at least stick with something that is at least registered in the said country. If that is not possible, try your luck with a casino that is licensed in countries where a license actually means something, like the UK.
Also, never forget:
Do you know your rights as a gambler?
