There are many gamblers around the world and they have different perspective and different way of handling their emotions some of them are when playing and after a big win they will stop or pause for a while cause they have the perspective that once they win a big amount they must stop inorder to prevent more losses. While other gambler can not control their emotions and when they are playing and win they don't mind anything and still betting and betting without knowing that after a big win they will loss and loss until all theirs money got loss.
If you're giving out only two examples of gamblers then that means that your claim that there are many gamblers that have a different perspective isn't true then? In terms of perspective, yes that can be true as each individual was raised differently and came from different environments but I don't think that you're wrong about those two examples and I think they're the only kind of gambler or that you can group gamblers in that two category, maybe if we dissect the nuances of each side, maybe that's when you're right that there's different kinds of gambler.
Responsible gambling in my opinion is relative to how much money you've got and how much you value the money that you've got, if you're the kind of person that doesn't mind losing a lot of money but you've got a lot of money then I don't think that you can ever be responsible and it's true with the opposite, that you're totally responsible with your gambling habits if you value the money that you put into it.
