Do I really need conda at this stage?

So I am conflicted on whether to install miniconda or not. When I started deep learning a few years ago, I literally installed tensorflow, keras, pytorch using pip so when i do the pip freeze thing its attached to the default windows interpreter. The question is, should i delete everything on there and reinstall all modules using conda or just not worry about conda? I have low space so i have to delete one or the other.
