I would like to install VirtualBox as an Ubuntu testing environment. Must I permanently sacrifice system resources such as RAM? Or only when the environment is running?

You must sacrifice some disk space when you install it.

And a minor part of RAM, as it loads additional kernel modules.

Nothing more, as long as the app is not running.

The ressources you assign to a virtual machine are different:

of course its virtual disks/storages will be there until you delete that VM and its files

the RAM assigned to the VM will only be used when you fire up the VM and should be freed once you power it down.

Same for the RAM VirtualBox itself uses to run, which should be freed when you exit the VirtualBox application itself.
