…But I think people can be afraid of heights without past experience of falling…
I have seen it claimed that crawling-age babies are afraid of heights, in that they will not crawl from a solid floor to a glass platform over a yawning gulf. And they’ve never fallen into a yawning gulf. At that age, probably all the heights they’ve fallen from have been harmless, since the typical baby is both bouncy and close to the ground.
