That's correct for the default configuration, 127.0.0.53 is the cached
DNS server on the system itself.

To see the 'upstream' DNS servers you are using try 'systemd-resolve --status'.

However this may just show the address of your router, which *is* the
upstream DNS server on most LANs.  If you want to know what public
servers you are using you may have to look in the router's
configuration.
