Yep! And luckily Tor Browser works pretty hard at defending against that. It even goes so far as to box the rendered page resolution so it cannot be connected to the same resolution as your main browser.
But you can take first steps by using a simple dns proxy to make things more difficult.
Honestly that probably makes it easier to fingerprint you. How many people do you think actually use Tor? Instead of needing to identify you from millions of users, now they just need to identify you from the five or so Tor users
I don't mean that, I mean behavior. The algorithm that is TikTok is running a test fingerprinting you with every video shown. It's like stylometry on steroids.
