What does a delivery report not requested mean?

I'm getting a delivery report of not requested when I send a text message on messaging app..does this mean I'm blocked

Welcome to Android Central! Which phone? Is this the stock messaging app? Do you have the option for delivery reports turned on in the first place?

Could be mistaken but I believe it means the person who read the message isn't using a messaging app capable of notifying you if it was read or not.
