My guess is that they are end-to-end encrypted. And because of Facebook's scale that they're able to probabilisticly guess at what's in the encrypted messages (e.g.a message with X hash has Y probability of containing the word "shoes")
That seems unlikely given that they use the signal protocol: https://signal.org/blog/whatsapp-complete/

That's not how encryption works at all. At least not any encryption used in the last 100 years.
You'd probably have to go all the way back to the encryption methods of the Roman empire for that statement to make sense
That would still be very close to educated mind reading
