This all comes down to how you define a real job. Is a job something that pays the bills? Is a job something that gives personal satisfaction? Define "real job" in your paper first, without even thinking about youtube. Once you have your definitional framework, just apply the attributes of your youtube channel to it and the answer will come to you. To me, I would say yes, it can be.
I think of it like being an actor. Is is a real job? sometimes? how good you are and the name you built for yourself will allow you to get paid more or less, coupled with how much you work.
The only real difference between us and other positions is that we deal in views, not in hours or projects.
We are essentially under the same umbrella as ad salesmen and bloggers and people that run forums.
