They overlap. Wikidata uses generated URIs for entities, properties, etc. that are not human readable readable; they can be resolved by hovering the mouse cursor on the SPARQL endpoint web app or add a pattern to get the label for these URIs.
Many of the Knowledge Graph people who I have worked with clearly prefer Wikidata but I am in the other camp: I find it so much easier using the human-readable meaningful URIs for entities, properties, etc. in DBPedia. Yesterday I wrote SPARQL queries for both DBPedia and Wikipedia.
