YouTube is after all a form of social network. You can comment on a lot of videos and get subs. Think of the guy on this forum that got to 1,000,000 subs without posting a single video. Problem is, it doesn't help you get views. If anything it hurts in the long run. But maybe she's never planning on posting videos. She just wants to be part of the community. Either way don't stress it. I never care about a channel's sub numbers.
