N in M fractions are used in casual copy to convey an approximate value. Finding a "1 in 4" number on a dated website does not mean that the current number is literally 25%.
It's an approximation and not meant to be taken as a precise value. They're not going to update the website to "26 out of 100" if the number changes.
Citing an old, approximate number in some non-specific website copy does not invalidate anything.
