No, which I went on to admit in the stuff you snipped. ;-)

I'm not sure this is better; it would definitely have a
higher cache hit rate, but the lookups are significantly
more expensive (fetch the wordinfo, extract the counts,
then fetch the probability).

Something to measure...

I moderately agree, but OOP folks tend to have an aversion
to pure data classes (as I think WordInfo should be). ;-)
