Well, this is Marseille, France and this is how your ISP routes the traffic to Cloudflare's address(es). You can repeat the same command several times and also change 1.1.1.1 to 1.0.0.1 and see if the location is changed.
What you see in the browser is completely different story. If you want to test your router you should disable secure DNS in your browser so it will not talk to Cloudflare directly but rather use the system DNS assigned by the router.
