What’s the real difference between AI and Machine Learning?

I keep seeing AI and Machine Learning mentioned everywhere, but I’m still a bit confused about the exact difference. From what I understand, AI is the broader concept, and ML is a subset of it but where does one stop and the other begin?

For example, is every AI system using Machine Learning, or are there AI models that don’t rely on it at all? Would love to hear how you all break it down!
