I am pessimistic that it will succeed in making the gambler responsible as desired because gambling is not like the count of mathematics in the sense 1+1 = 2.
Gambling for most elements is not seen from a positive point of view so that I can say that stakeholders in countries in the world will not make official gambling schools to be taught how to become responsible gamblers.
In some countries, gambling is legal within certain age limits. In those countries, I think gambling schools might be one interesting idea that could be developed, but I'm not sure if such schools already exist. As far as I know, gamblers learn autodidactically from various online sources to become responsible gamblers. There is a lot of content they can read and learn about and how to best approach gambling so they become responsible gamblers.
Offline school may not be a good idea for most countries where gambling is legal, but this also really depends on who the leader of the country is. In fact I tend to believe that the idea of creating a gambling school would be rejected by most of society, but who knows.
