Yup. though a lot of things are more effecient and easily understood with GUIs than command line interfaces. Imagine a volume slider. on the other hand there’s a lot of things that are much more convenient in a terminal window.
sure. you can use
amixer sset Master 50%
to set volume to 50%, but it’s faster and more intuitive to use the GUI for it.
As you said, that’s an example of a CLI, yet a TUI would be something different, e.g. like the non-graphical installer of your dear Linux distribution.
