Yep, and it's not just a childhood thing. At any age, simply listening to a lot of vocal music (with very light accompaniment) helps a ton in improving your singing (alongside other active work)

We probably have some instinct for vocal imitation, to intuitively understand how the sound we hear is made - otherwise, it would be hard to learn to speak.
