You described reasoning by analogy, which two thirds of the population does.

Please explain explicitly what you are implying, because I don't get it

Who are the 1/3 of the population that does not reason by analogy?

Instead of needing a familiar metaphor to understand a new system (reasoning by analogy), they grasp the core conceptual mechanics directly.

It’s not that the 2/3 can't think abstractly, it’s just that they use analogies as a temporary processing step to get there, while the 1/3 starts there.
