I wouldn't put much thought on Youtube Red when you're still growing. Let YouTube handle how they will showcase your videos on that platform. Right now, it's essentially only beneficial to those that actually have YouTube Red shows produced by YouTube themselves.
YouTube red is going to save you time when watching YouTube videos. No more ads. But I am not bothering with it. This hobby costs enough already, and I have all the content I need in the form of Netflix and Amazon Prime that I really don't need YouTube Red with it as well.
