In recent events, I learned that some pagers only have receivers. How are discrete messages sent to these devices? How is it authenticated? How do they know the device got the message?

They're sent like a phone call. Afaik there is no confirmation on the network whether the device received the message.

So they just broadcast the messages from all the towers in the network? In plain text I hope.

Yeah it’s not as secure but it has privacy advantages since there’s no 2-way communication.

But... 2-way pagers also exist. I've known nurses that had them for work.

Yeah and my guess is that they’d be less private because if they act as a transmitter, I think they could potentially be triangulated.
