Not conflating anything. For example, systemctl will present results in a less/more like ui which is more tui than cli. gh is interactive, but it's about as TUI as a CS120 print and input exercise (and not much more advanced than a progress bar). There are a bunch of tools though (XXXcat type programs, systemctl, file transfer clients, mail clients) that go full TUI when invoked without CLI only parameters. There are even GUI apps that can be invoked from the CLI and run without the GUI. It's really common in unixland. What is awesome is to see interest in TUIs again. They are so productive.
