This is because when you click a shared TikTok link, your account and the sharer's accounts are associated in a social graph. The sharer will see your account as a suggested friend and vice versa.

No sharing link needed. Before I deleted my Facebook account more than a decade ago, it was already suggesting random people I met once IRL and are at least two hops away in terms of existing FB relationships. I had very few friends (~20 IIRC).
