Yeah, I've always felt it foolish for streamers/Youtubers/etc to put all their eggs in that basket and having no backup plan. However, she said she does plan on continuing her education, getting a degree, and graduating. She did say "Maybe going to this university to pursue that exact, specific thing isn't what I need to be doing and maybe just doing something a little bit more...broad?" So she'll have that as well.
I think she'll be okay, and she can continue being happy with what she's doing now. I'd honestly be a little worried about her mental state if she had to give up VTubing at this point for school.
