The idea can be adopted but it shouldn't be mandatory. The purpose of every gambler coming to a new casino for the first time is to have a good experience depositing, gambling, and withdrawing their funds. Having to go through some series of questions for whatsoever reason may look too tiring for many gamblers they will rather leave the casino and move on to the next option.

Like I said it should be of free will for the gamblers to pas through this quiz. For those who want to learn through the quiz let them click the option by themselves. Any feature to be added to a casino should be checked if it improves the user experience for the gambler. If it does not then it shouldn't be implemented in the casino. The headache of losing and the problems that some casinos give to their user is enough already.
