Not entirely true. Your mentor might be referring to UDP broadcast, in which case everyone in "earshot" (subnet) can hear your message.
(S)he might also be referring to UDP on a hub, in which case everyone attached to the hub hears the messages and dutifully ignores them as appropriate.
However, the default usual use case for UDP is from one source machine to a specific target machine.
