I think they only compete in the space of short videos and mobile devices. When it comes to longer formats and non-mobile devices YouTube is just the de facto content provider of user-created content. Like, I lay on my couch and watch YouTube for hours. Car reviews, NBA highlights, documentaries, cooking recipes, travel tips, etc...Not a space/device TikTok can enter easily.
