I had this thought just now at the gym. I noticed multiple people, myself included, using wireless earbuds during our workouts – specifically AirPods.
My question is, if multiple people are using AirPods that work on the same frequency/signal, how come our music doesn’t all interfere with each other? How do each of our phones/AirPods differentiate from the others a few feet away from me?

If you were on a conference call or just like a crowded restaurant or something, there can be several conversations going at once. It doesn’t all have to be 1 conversation. Even if there’s some other noise going on.
Each person just speaks with a different tone of voice, and you listen to the voice that matters to you while ignoring the rest.
That’s basically what the Bluetooth devices are doing. Just listening to the frequency that matters to them.
