It’s important to understand that many distro’s are usually based off of another.

We got Debian based distros such as Debian, Ubuntu, PopOS, KaliLinux, LinuxMint and so on, Arch based distros such as CachyOS, SteamOS, Arch and so on and Fedora based distros such as Fedora, Nobara, Bazzite.

Once you learn one of these base distros switching to another within its field is easy as majority of shell commands will be identical.
