Why is Linux giving a pts number for real terminal console? (which is not an emulated terminal like ssh or xterm)

Question

I read that pts is a pseudo-terminal (that we get through ssh or xterm) and tty is the native terminal.

I didn't connect to my PC through ssh or xterm, but I am still getting pts/0 and pts/1 when I type who command. When I open other terminals, the number of pts's increase.

username@machine$ who
username tty7         2020-12-30 11:39 (:0)
username pts/0        2020-12-30 11:39 (:0)
username pts/1        2020-12-30 11:53 (:0)

I am not getting why this is happening, shouldn't there be more tty's after opening other terminals?

Also, when I do su I see that other pts session gets opened for root in auth.log file.

Answer 1

as you already hypothesised in your comment:

Okay so the GUI terminal application is also considered as pts and the only tty would be that system's main shell. Like through alt+ctlr+F2 and maybe also through grub. right??

a GUI terminal emulator (be it xterm, gnome-terminal etc) does not open a native terminal (tty) but a pseudo-terminal (pts).

native ones are only those that you reach by pressing Alt+Ctrl+F2 etc.
