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.
