I created a virtual environment using venv module of python.

python -m venv myenv

After activating environment using source myenv/bin/activate, I am getting systemwide packages already there in the myenv. I am getting strange result as:

(myenv) $ pip list
Package       Version
------------- -------
pip           20.0.2 
pkg-resources 0.0.0  
setuptools    44.0.0 

and when I do

(myenv) $ python -m pip list
#...Getting long list of packages present in the systemwide python packages

I failed to understand this strange result

System details: OS: Ubuntu 20.04 Python: 3.8.10

Edit: Here is the location of pip and python packages

(myenv) $ which pip
/home/user/myenv/bin/pip
(myenv) $ which python
/home/user/myenv/bin/python
