I think you should look into the arch wiki to get yourself familiar with the base Arch system.
Arch is not Debian/ubuntu and doesn’t use APT or snap.
Archs package manager is pacman: pacman - ArchWiki
As it was said, we don’t have apt here because Cachy is based on Arch which uses its own package manager “pacman”. It can be somewhat confusing when you just switched to arch (see “man pacman”, so you can install some pacman helpers, for example Pamac use command syntax more like apt, see also paru and yay.
Same goes for snap, i think no one use it but Ubuntu, I heard someone installed snap on Cachy but by default we use Flatpak instead. So it’s not a sudo issue, sudo worked here as it should — attempted to run something as superuser.
Regarding uuuum oracle vmware? Oracle has VirtualBox, and vmware is a separate company with multiple virtualisation products, I don’t use neither but can assume that installation process will differ. What i use is Gnome Boxes, which relies on virtualisation capabilities already built into Linux kernel and it worked for me without any problems. You can get it in CachyOS Package Installer (just as virtualbox apparently though I didn’t try)
For docker I don’t know what issues you had but it also can be installed from Package Installer
