Wat? What dependencies? I have right now 100 separate Python projects which each have their own venv, their own isolated dependencies, and their own isolated copy of Python itself and my code dir doesn’t even crack top 10 hard drive space.

Machine learning packages like Tensorflow can result in GB size package directories.

Yes, the biggest available library is big, that's hardly an argument though.

A really common library that gets used in every project for common use-cases is big.

It's a very good argument.

No, saying "one common library is big" isn't a good way to show that "Python dependencies are big", which is what the initial claim was. Most libraries are tiny, and there's a very big one because it does many things. If Tensorflow were in JS it wouldn't be any smaller.
