I fixed my issue by...
downloading Python 3 at the official website and installing it via express installation
Copy & Paste the standalone python into the ampps/python folder and overwriting the python version provided by AMPPS
running python -m pip install --upgrade pip in cmd
Now pip and python 3 are installed in their latest version.
It seems that AMPPS doesnt't provide a full-fledged python build. So you need to update python yourself.
Thanks to y'all.
