You're wrong, it does not.

You can install a pip package in a conda env. But this is actually not recommended.

When using `mamba install` or `conda install`, pip is not involved at all.

You’re correct, Conda does not call pip when it installs packages. But pip does have a subtle involvement here: Many Python packages available to Conda are packaged based on installations made by pip, and (IMO lazily and incorrectly) inherits a lot of pip characteristics. This makes the packages “appear” to be installed by pip, and sometimes induce interpolation inconsistencies.
