Morphology
The meaning 'one after another' is directly and compositionally derived from 'one' (a single unit) combined with 'by' indicating distribution or sequence, so a learner who knows the constituents can infer the phrase. This per-unit/serial pattern is cross-linguistically common and follows a transparent English construction, making it immediately comprehensible to a B1 learner.
Etymology
One by one paints a simple picture: imagine people entering a room, each one coming through the door after the last person. So it means 'one after another', not all at the same time.
