this does sound funny but what do you do if it turns out that your culture requires you to play gambling?
If it is the detect of the culture then nobody under the culture will go against it at least for the beginning of the practice of the culture but if there are changes as a result of acculturation, it will happen that the culture will begin to be altered and changed.
One of the ways that cultures get modified and changed into another culture is through acculturation which is addition of culture to produce another brand new culture and of course culture is man made and if it is obnoxious type that is contrary to good life, then people can start agitating over it. Therefore I believe there will be limit and requirement that you can gamble for the sake of the culture and not to become an addict with it.
