Following on to your comment, is this, "TikTok’s algorithm is designed to learn what type of content users like", what almost all social media does to a certain extent?
at this point yes, TikTok's has been better at it and others have been playing catch up trying to replicate it and its interface. For example, Instagram's Reels are like TikTok's, except Instagram's users are split doing a dozen other things, while TikTok's users are only doing the "reels" like feature and associate TikTok with that.
