These days gambling have turned to be a part of one's hobby. This is the reason we can see majority of common people who are little knowledged about technology are into gambling. Another important reason for the increased participation into gambling by the present generation is through the advertisement broadcast on the television. This doesn't have anything with the inheritance.
I agree with your first reason that technology in this generation is one of the reasons why gambling is becoming a hobby, the internet and smartphones are available to everyone who can find information can be provided, just like visiting websites and installing mobile gambling-related games and applications. But the advertisement that can be broadcast on television, was vague because as far as I know, there are laws that prohibit it. It just depends on the policy of the country's ministry.
