Writing replies in a chat app is learning to type. Typing is a job skill, people used to pay for typing classes.
If, in the chat app, you create literature, you're creating literature. Some people are, most people aren't. If, on tiktok, you create interesting short films, you're creating interesting short films. Some people are, most people aren't.
To sum up, I agree with you that "doing tiktok" is like using a chat app, and agree with you that it's not necessarily educational. I disagree that it's necessarily not educational.
