Question

What is the difference between machine learning and quantum machine learning?

Answer 1

The difference is much simpler than you might have anticipated: In the quantum computing community, machine learning algorithms designed to be used on quantum computers as opposed to classical computers, would fall under "quantum machine learning". There's really nothing more to it!

There is a short paper published in Nature called "Quantum Machine Learning" which was mentioned before, and it might give you all the answers you need about what "Quantum Machine Learning" is.
