Up until April 2021, no, unless someone hacks your drone, or are a government entity with tracking hardware, your GPS coordinates are safe. However, beginning April 21, 2021, the FAA is enacting Remote ID requirements. Part of these requirements are to broadcast both telemetry about your drone, and the coordinates of your controller, or at least the coordinates from where the drone took off from the ground. Anyone within RC broadcast range will be able to see you and your drone on a map. Your personal info remains safe, but your location becomes public.
