I dont know much about it, but Wikipedia says that MTProto is specifically for "secret chats":

For encrypted chats (branded as Secret Chats), Telegram uses a custom-built symmetric encryption scheme called MTProto.

https://en.m.wikipedia.org/wiki/Telegram_(software)#Architecture

Maybe Wikipedia is misleading here

You're right, it is misleading. There are different "flavours" of MTProto. See here:

https://core.telegram.org/mtproto

This page deals with the basic layer of MTProto encryption used for Cloud chats (server-client encryption). See also:

  • Secret chats, end-to-end-encryption

  • End-to-end encrypted Voice Calls

(The major difference is simply whether the server and client share a key or two clients)
