That sounds backwards to me, and a quick check comes up with these numbers:
Supercharger: 7,320 globally and 443 in the USA
CHAdeMO: 23,000 globally and 1677 in the USA
Edit: Those numbers above aren't fair. As I look further, some counts are for "stations" and some "charge points", so numbers I found earlier are not comparable as they are from different times and sources, and are counting different things.
But I did find
a recent USA only comparison that comes from official numbers:
CHAdeMO: 2140 locations with 3010 outlets
CCS/SAE: 1888 locations with 3525 outlets
Supercharger: 678 locations with 6340 outlets
