Output from tty is different comparing to output from 'who' when on a single terminal

I am on WSL 2 running Ubuntu.When I open terminal, it directly logs me in without asking credentials.This is the only single terminal that is open, why do I see different output:

output from tty:

mshah@NL-1023517:~$ tty/dev/pts/0

output from who:

mshah@NL-1023517:~$ whomshah    pts/1        2025-04-21 18:19

If 0,1,2 are link to descriptor for stdin, stdout & stderr respectively in pseudo-terminals, why do I see only 0 & 1 in
ls -l /dev/pts

mshah@NL-1023517:~$ ls -l /dev/ptstotal 0drwxr-xr-x  2 root  root      0 Apr 21 18:19 ./drwxr-xr-x 16 root  root   3580 Apr 21 18:19 ../crw--w----  1 mshah tty  136, 0 Apr 24 05:17 0crw-------  1 mshah tty  136, 1 Apr 21 18:19 1c---------  1 root  root   5, 2 Apr 21 18:19 ptmx

Also, output of pf -ef shows:

Q) With only one /dev/pts/0, why does it show that I am logged in from /dev/pts/1
Q) In processes (ps -ef) why are two bash processes running under my ID when I have only one terminal open?

I read this& this, but it is still not clear and if someone can help simply bit more, really appreciate it.
