Yes, most likely an unprepared reader of such posts and messages with claims against the casino, who is not familiar from the point of view of knowledge of jurisprudence and the ToS provisions of any casino, will not be able to figure out who is right and who is wrong.
In general, I don’t really understand the motives of those people who start discussing complaints about casinos in the public space simply because there is a very low probability that someone will write sensible advice. Maybe such cases do happen, but in my opinion this is rare and the whole discussion usually comes down to sympathy for the victim and cursing at the casino and their ugly support. Maybe, of course, this is a hidden form of anti-advertising. But this method is somehow too sophisticated.
But with the exception, of course, of the well-known mass claims such as 1xbet.
I think that in the social aspect many people have this belief that at some point they must win or win in a casino, and when they lose a lot of money they see it as very bad and therefore they do not like it and they start to make accusations to see if they can find some kind of support, however they do it without foundation at the regulatory level , they are the ones who say yes to the Tos without even Reading a little and at least Realizing what it is about , so it is difficult because it is not how they think, but how it really is.
You looped this together IMO as losing is a different context from not reading the terms of service. Anyone who is guilty of not reading the ToS should just be disregarded as the casino will always be vindicated in this regard.
Again, the casinos will not be at fault if the gambler is unwilling to accept the known loss. Gambling has its rules and we must obey them, otherwise, the gambler should avoid it (gambling) and find other things to do. I do not understand the reason why a gambler would not want to agree to a loss when the casino did not cheat in any way, it could only mean that the gambler is just a "child in thought" because every mature gambler should know that gambling is either you lose or you win. I don't know what is difficult for anyone to accept in that but rather have plans to cushion the effect of any losses.
