If you revoke location permissions, Google still guesses it accurately, for me at least, "from your search history", as it says at the bottom of the search results page - even when you're not signed in (screenshot: https://imgur.com/a/wU8EZUA). I wouldn't mind if they just used the IP address to locate me, but why use the search history? If I wanted Google to know my exact location, I wouldn't have revoked the permissions for it.
