Troubles with installing kvm/qemu

I am following a tutorial online where someone is installing KVM/Qemu on Fedora and I am noticing almost NONE of the terminal commands are working.

For example, sudo dnf install --with-optional virtualization gives me nothing, while installing everything this person needs to get started.

I am really struggling with understanding what system I am working with... is it Fedora based? KDE based? and then more importantly, am I even able to create a Windows 10 VM with gpu passthrough on Bazzite?
