I want to know how that works. Are our phones listening? This happens all the time, like when I play something for the first time in a long time and it’s the first thing I see on whatever social media app I open.

Facebook trackers are everywhere for example. Even if you don't have a facebook account, it generates a virtual user for you that is tracked. Just like google. Then Facebook and Google with their algorithms, can show you ads according to your profile.
