It get stored in site-packages folder eg C:\Python37\Lib\site-packages\numpy

Python locate it for you when using import,you never need to go yourself to site-packages folder.
C:\
λ python
Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 21:26:53) [MSC v.1916 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>>
>>> np.arange(15).reshape(3, 5)
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14]])
How it work as looked upon from outside.
Windows find Python when it set in Environment Variables Path,this get done automatically under install if mark on eg Add Python 3.7 to PATH
Python finds files(module/package) by looking in sys.path.
>>> import sys
>>>
>>> sys.path
# List get back here is where Python look
