Just as you use "which python" to figure out what "python" was executing, >"which pip" will help you figure out what "pip" is running.
root at secure [~]# which python3
/usr/bin/python3
root at secure [~]# cd /usr/bin/python3
-bash: cd: /usr/bin/python3: Not a directory
root at secure [~]# which pip
/usr/bin/pip
root at secure [~]# cd /usr/bin/pip
-bash: cd: /usr/bin/pip: Not a directory
