Not a tiktok user, but I know instagram also fills your explore feed with the content that your friends like. So even if you're tailoring your likes to appropriate posts, your friends may not be.
That may just be the initial period after a user has signed up and hasn't engaged with enough content for IG to show anything under "Discover". They may use friends' preferences as a placeholder.
I know for a fact that what's on my Discover feed (surrealist art, UX/UI stuff, Newfie dog videos) is unique to me.
