This is a really good way of explaining the difference.
So, UDP just sends it out there and anyone can intercept it?

No, instead of using TLS for encryption (like most TCP traffic) UDP will use things like DTLS and SIP

Or if you’re asking about the actual transport it’s more like TCP is going to your friend’s house and calling your mom to let her know you’re there vs UDP is going to their house and not calling.
