Blender comes with Python, and includes a stand-alone Python executable. However pip is not part of the official Python distribution so it needs to be added separately.

pipwith Blender's bundled Python so it can be used to install Python packages from Pypi which are then available from inside Blender? - How would you use it to install a package?
Note, this is related to this question, but not a duplicteduplicate since its not about using pip as a library.
