According to Science News, if you pick a random point in the part
of the USA that is most prone to tornadoes, you can expect that
point to be hit by a serious tornado about once every 4,000 years.

Except that tornados aren't distributed randomly across the US; there
are areas that get a lot of them and there are areas that get few of
them.

Yes indeed. Did you read the article I cited? It takes that into account.

The 4,000-year figure is for the parts of the country that get the most
tornadoes.
There are areas where the figure is millions of years, rather than
thousands.
