TikTok’s recommendations are based off as much info as it can get, really.
Approximate location, age, mobile OS/browser, your contacts, which TikTok links you open, who generated the links you open, TikTok search history, how long it takes you to swipe to the next video on the for you page, etc.
I don’t think it's really possible to say what TikTok’s algorithm does “naturally”. There’s so many influencing factors to it. (Beyond the promoted posts and ads which people pay TikTok to put in your face)
If you sign up to TikTok with an Android and tell it you’re 16, you’re gonna get recommended what the other 16 year olds with Androids in your nearby area (based on IP address) are watching.
