In the DataCite Metadata Schema resourceTypeGeneral is one of the six mandatory properties with a controlled vocabulary list of 28 different values that describe the resource. The list includes values like Dataset, Sound, and Model. There are currently around 49 million findable DataCite DOIs. The easiest way to see the distribution of DOIs by resourceTypeGeneral is via the REST API.
You can run an unqualified API call like this: https://api.datacite.org/dois
At the bottom of the response you will see the meta values in "resourceTypes" contain information about the number of DOIs by each of the controlled vocabulary values.
