Google Searches showing up in TikTok Results ?

Searched for noodle shops in my area, horse riding lessons for my kids, door hardware, etc., over last 2 days, all on Google Chrome on my desktop in U.S., while signed into my Google account. Now within a span of eight hours, getting tons of ads for those EXACT things on TikTok.

Does Google share personally identifiable data with TikTok?
