AI vs Machine Learning vs Deep Learning

Let me tell you a story, before I get into the topic -- I am a Computer Engineering Student and it was my first year of college. And, Everyone was suggesting me to study and specialize about "AI and Machine Learning(ML)" because they say it is a high demand and a high-paying job. Of course, I agree with their ideas and the reasons. But, whenever I asked: "What is AI or ML?" Mostly everyone said to me -- Its the same i.e. teaching computers to behave like a human. My point is: Most people don't know and they are confused about, what is the small difference between AI, Machine Learning and Deep Learning?
