Machine learning is a broad field of techniques; deep learning is an area of machine learning that I think generally focuses on neural network techniques, and usually rather large networks at that. Machine learning in isolation doesn't necessarily mean neural network techniques are used at all. Nor does deep learning exclusively mean neural networks, but usually "deep networks" are a part of it.
