Ági Szabados is a 35 year old adult woman who runs a successful nationwide book club. "Young content creator" in this context absolutely is patronizing.
I find 35 young. Young != not adult.
Having a successful nationwide bookclub does not stop her from (apparently) being a content creator. And vice versa, being a content creator does not diminish the success of her bookclub.
You seem to suggest that being a content creator is somehow "less worthy" than having a bookclub. Many people are super successful being content creators on YouTube. Are they less because they don't run a bookclub?
Sounds pretty elitist to me
