Gaming Reality

Answer me this one then.

Sure thing.
Being an addict would mean that gaming took priority over other and more important things in your life, for some SC2 players gaming is their job and thus, it doesn't take priority over their job because it is their job.
Many teams and players in e-sports almost regardless of the game aren't able to make a living from playing, and thus still have to prioritize other things such as work above it.
Enjoying and spending a lot of time on something =/= Being an addict. I do not get how people can assume that spending a lot of time on something means that you are addicted, there are many many people who use a lot of time on single activities in their sparetime without them being addicted, hobbies exist you know.
For you to be a pro gamer you'd have to make money, because "A professional is a person who is paid to undertake a specialized set of tasks and to complete them for a fee. "
Being sponsored makes you a professional team.
Being addicted on the other hand is to be "compulsively or physiologically dependent on something habit-forming". And being computer addicted is often defined as "the excessive use of computers to the extent that it interferes with daily life." and you are able to use a lot of time on playing games without it interfering with your daily life(bathing/working/eating/sleeping/everything else you'd need to do)
And as i've already stated, you can use a lot of time on something without you being dependent on it, at all.
I personally have large periods where i use 4-5 hours a day reading books, often multiple book series and triologies, this can span over a few weeks. Does this make me addicted to the books? No, i just enjoy them and have time to use on it.
