All gamblers both new comers and old ones are awared that there are two things in gambling either to win or to loss so there is no too much awareness again about the dangers of gambling. They are already awared before coming to the gambling section. All casinos are meant to make profit so if they are meant to beat you then it is their luck and if you beat them then you win. And that is why before you play a new game in casino site, you have to read the T/C and probably if possible learn how to play the game before playing the real game so you will know how to play the game. The things Op mentioned before navigating to a casino site are all God to know before embarking on the casino site.
The thing concerned by @OP's post is that not to be able to withdraw winnings from newly created casinos, so @OP is reminding us to check thoroughly. This is not a matter of knowing or being aware of winning and losing, the discussion is a matter of not getting scammed by new casinos because we got lapses and lazy to check the needed information before diving into the platform and play.
Rouge casino have pretty much the have same terms of service as the reputable one, they are good with pretending to be a legit one in terms of documentation so we need to check for other factor that may identify the newly established casino a promising one or just a rouge one that can scam its player anytime.
In some point I agree with you that before a player choose a game he must do some research about it, maybe trying the demo version is a good way to see the mechanics of the game.
