The big caveat there is that the US is, by design, horrible at counting homeless people. The official number you see the most, 582.000, is based on people going out in the street and counting the number of homeless they actually see that night, and the number of people in shelters. Obviously that’s going to miss a LOT of people, so the number is much higher in reality.
That’s not to say it’s a fucking crime against humanity that there are houses sitting empty for years while people are homeless, of course.
