Is WhatsApp listening to my conversation

I was talking to my husband over a WhatsApp call today and we were talking about knee surgery as one of our relative met with an accident and had to get a rod implanted. And not even a day has gone by and I get a reel on Instagram on how a knee surgery is performed. I didn’t search for it.. neither do I watch any similar content. Is it just a coincidence??? Cause this is not the first time …
