Software packages that are different

What makes one distro different from another, is that it might come with gnome instead of KDE, pacman instead of apt, initd instead of systemd, systemd-boot instead of grub.
So...different software? Those are all software.
That’s literally where the name of “distro” comes from.
The name comes from different distributions of Linux that come packaged with different software .
