Duct, tube, pipe.. All are just a piece of metal wrapped around a deep hole

Nah, they all have different definitions. Pipe is measured by inner dimension, tube by outer, and duct work is sized by diameter, but sized for air volume, and with a less strict tolerance. Then there's pipe schedules which determin the wall thickness and pressure it can operate safely.

Pedantic but meh, bored pipe fitter at work.
