In 18.104.22.168 Automatic Degree of Parallelism can only be used if I/O statistics are gathered.
The AutoDOP is not a feature to use more parallelism. It is a feature that restricts the parallel to maximize throughput,
so it is expected that with AutoDOP not all queries will run in parallel and the ones that do run in parallel may not run with full parallelism, as this is the technical specifications of the feature.
