Do you provide location data to Google and submit to their stalking?
If Google gets hints from a variety of sources (some hard-to-fake like nearby cell towers) from someone that has been feeding them plausible data for years, they will believe those hints more.
If you don't give them the same hints (such as by not using Android or Google products, running ad blockers, not having a Google account with verified and hard-to-fake location-dependent payment information such as a card from a local bank), then it's somewhat reasonable for them to go by the info the other person is providing.
