Since you say "accurate" then we can direct to the real definition of gambling based on our own dictionary or any web search engines. And that's the one you already post.

Does it have any accurate answers? What do you mean by here?

As for what kind of gambler are me, I think this is like, introducing yourself to everyone. Gambling for fun, gambling for money, gambling as a sideline, gambling as etc. I don't see any further discussions needed at this type of subject unless you are collecting data for something.
