Maybe it's different at expensive private schools in the US, but the vast majority of Americans never attend those schools.

It's about 63% of high-school grads, including both 2-year and 4-year colleges: https://nces.ed.gov/programs/coe/indicator/cpa

I believe they are actually measuring any time enrollment in that period. Otherwise the statistic seems of little value.
On time high school graduation is achieved by around 86% of the population. This surely accounts for much of the difference.
63% is the statistic for high-school grads, whereas the person you're replying to is talking about all "18-24 kids", so "all kids graduate high school" is an appendix to assumption 1) you would need to add.
