Well the regulations are mostly for the minors and how the gambling sites and casinos pay their taxes. There can't be any regulation about how much anyone can gamble and how much they can spend. People can break their banks and go on debt. And that has been the case for the longest time so i don't think there can or will be something done about it
There are some countries who certainly do not take gambling as something that is reasonable for anyone to do and hence the strict law against gambling which apparently makes it entirely impossible for anyone to be a part of. However, this does not mean that even at that, some people still do not find a way to gamble once in a while and stay out of the government radar.
The culture though is dependent on how people generally within the society perceive gambling. We cannot expect anything beyond that, I mean gambling for only fun and stopping at right time are the things which may not be covered in most of the traditions as they do gamble for their own reasons and it is individual's responsibility to protect themselves.
