Yes.

Linux Mint, Zorin OS, Linux Lite, Pop OS, and several less famous distros are all based on Ubuntu. New versions of all of them will follow this new LTS release in time.

Mint forked GNOME 3 to make something more Windows-like.

Zorin customised upstream GNOME with a lot of extensions.

Pop removed it and replaced it with their own homegrown desktop, written in Rust. It's actually pretty good and works well.
