There are 16 CHAdeMO charging points in the US.[1] Most of them on the New York Thruway between Albany and Buffalo. There are two in San Francisco and two in Marin County. That's it.
But, for the most part if there's a Chademo plug there's one or more CCS. A Chademo only dispenser is practically a unicorn these days.
You are wrong by a factor of over one hundred.

Yeah, except for the thousands of chademo charge points outside of your microscopic awareness. https://www.energy.gov/eere/vehicles/articles/fotw-1139-june...
Plugshare, which is crowd-sourced, shows far more CHAdemo chargers.
