 If all vCores of an elastic pool are busy, then each database in the pool receives an equal amount of compute resources to process queries. The SQL Database service provides resource sharing fairness between databases by ensuring equal slices of compute time. Elastic pool resource sharing fairness is in addition to any amount of resource otherwise guaranteed to each database when the vCore min per database is set to a non-zero value.
