When I run the following command it returns me the information of my current mouse:-
$ xinput --list | grep "Mouse" ⎜ ↳ A4Tech USB Mouse id=13 [slave pointer (2)]
What command should I execute (maybe along with some regex) that I can get an output 13
(in current case).
Something like this:-
$ xinput --list | grep "Mouse" | ANOTHER_COMMAND 13

Answer
xinput --list | grep "Mouse" |grep -oP 'id=K.*?(?=s)'
Or even shorter :
xinput --list |grep -oP 'Mouse.*id=K.*?(?=s)'
