You can only plug 20 cords into 10 duplex outlets, and most of these loads are
likely small enough and diversified enough so this wouldn’t be a problem.
A piece of equipment with a NEMA 5-20P plug would be one of those conditions.

Standard house wiring usually contains a string of about 10 15A 120v
receptacles. This is perfectly legal, so technically one could plug in 30 15
amp devices in all of them on the one circuit. This is why the circuit is
protected by a 15A breaker to limit the current draw on the entire chain of
outlets. Code only requires a "dedicated" outlet under certain conditions
based on the load item it serves. At that point it reverts to the mfg. of
the load involved and if they require it to be a dedicated circuit.
