I am trying to learn/experiment with some networking basics. I am on macOS with DHCP configured. I purposely removed the default gateway IP address (192.168.0.1) by going to the networking settings. I also confirmed there is no default route by running:

route get default
route: writing to routing socket: not in table

I can access Google Search and YouTube, but I can't access some other sites like superuser.com. What's going on?

You have only disabled IPv4 by deleting the IPv4 default gateway.
You have not disabled IPv6.

You are using IPv6 to get to IPv6-capable sites.

SuperUser.com, surprisingly, does not appear to be IPv6-enabled yet, which is why you can't get to it. Google's properties, including YouTube, are usually IPv6-enabled.
