Ok, you've installed python 3 on a Mac.

Historically most systems have shipped with python 2 (from the OS 
vendor, which is Apple in your case), and the "python" command invokes 
Python 2.  So python 3 is installed as the "python3" command to avoid 
confusion.  The "pip" command from your python 3 install looks like it 
is also installed as "pip3" to avoid confusion.

Yes, that is correct for this particular install.
