There are some big differences between American states, yes. (I myself have been to a few, not Idaho though.)

But there are even bigger differences between Indian states. All American states share a common majority language (English). By contrast, in India, different states speak different languages, even completely unrelated ones (Indo-European vs Dravidian). Yet I've never heard an Indian compare countries to Indian states.

There is also a fair amount of diversity within Australia, even within the same state. Sydney is a buzzing worldly metropolis of over 5 million people, at the capital of the state of New South Wales. 1187 km northwest, but still in New South Wales, is the tiny town of Tibooburra, population 134, which I actually visited once with my parents when I was a teenager in the 1990s. I think the difference between Tibooburra and Sydney is at least as big as the difference between Idaho and New York.
