Processing simultaneously is the purpose of parallel query execution, yes. But I see no reason for that not to work equally well for unpartitioned tables. Disk I/O is already pretty well optimized and parallelized, I think. Trying to parallelize a seq scan on the Postgres side is likely to yield far inferior performance.
