Gaming Reality

but being a pro gamer is still nearly impossible, at least right now.

Actually, plenty of not very skilled players can make a living trough streaming. And SC2 might be dominated by certain players, but a lot of other scenes have a lot of different teams playing for the top. And it's the same for normal sports, it's pretty damn hard to make a living by playing soccer, not a lot of people can do it.
You can go into pro-gaming without going trough addict gaming, playing a lot =/= being addicted. But yes, i'm not saying there aren't people who are addicted, there most definitely is.
