We use "parallel" explicitly to mean "running on multiple cores scheduled by the kernel".

Yes, but "parallel" is also used in CS to specify multiple things happening at the same time including IO.

Quote: "Parallel computing is a type of computation where many calculations or the execution of processes are carried out simultaneously."
https://www.wikiwand.com/en/Parallel_communication
Quote: "In data transmission, parallel communication is a method of conveying multiple binary digits (bits) simultaneously. It contrasts with serial communication, which conveys only a single bit at a time; this distinction is one way of characterizing a communications link."
So if 20 threads are making blocking IO calls, all 20 threads can make progress on those IO calls in parallel while having an additional parallel thread doing compute operations yielding a total of 21 threads executing in parallel.
