I am wondering about all the applications I use in Xubuntu. Is the Whonix method suggestive of using the Whonix workstaton to host all those apps instead of the host OS? What if I keep using the host environment?
Up to you. The ultimate way by Qubes(-Whonix) is to compartmentalize even more, doing everything inside VMs.
