That's purely speculation unless she privately mentioned it in DMs with someone, or actually started to dislike making that kind of content/exposing her body. It's not like she's Belle Delphine and made millions to just stop and live off comfortably.
She still seems young and I'd be surprised if she gave up early, on what might be her highest probable source of income which takes almost no effort aside from preparing the cosplays and doing her make-up... UNLESS she can make an already decent amount or more from whatever job her current experience can get her that supports her way of living.
