Since a long time i have been asking this question at multiple platforms but still unable to get any authentic answer. Please share your opinion.

I doubt you have an embedded GPS Chip unless you’re on a Most Wanted list somewhere . . . Just search on Privacy & Cookies etc. Tracking

Google track your location in various ways such as using your location History and web or app activity.
