Okay, but how do you then make sure that key isn't intercepted? Anyone who has the key can read your messages
They are talking about asymmetric encryption which has a keypair, private key (kept secret only by the owner) and a public key that is used by everyone that would send them a message. You can’t decrypt the message with the public key when it is encrypted using the public key, you must use the private key to decrypt it.
Ah, I missed the public key part.
That is true, you could do that

Yeah, they're a bit cart ahead of horse on that one.
