Tor Browser aims to make all the Tor Browser users look the same. That
is, the goal is to blend in with the other Tor users.

The goal *isn't* to blend in with "everything else using the Internet",
since that's a much harder goal.

See also the discussions in
https://tor.stackexchange.com/questions/11701/most-common-tor-browser-configuration-panopticlick

And see item 5 in the list under
https://www.torproject.org/projects/torbrowser/design/#fingerprinting-linkability

This question comes up every time there's a new Tor Browser release,
because somebody rushes to Panopticlick, finds that nobody else is using
the new Tor Browser version yet, and becomes concerned.
