Not your fault: the literature is a mess.
Domain events, event sourcing, and event driven are three different ideas that happen to share the label "event".
Domain events are a domain modeling pattern; in effect making "things that happen" a first class citizen in your domain model. Think

Event sourcing is a data modeling pattern; instead of having a domain entity with mutable properties, we have a domain entity with a history of changes.
Event driven is a communication pattern; system A publishes an event, and system B reacts. Notice that system A and system B don't even need to know about each other; the only need a common undertanding of the event, and shared plumbing (aka middleware).
