The ratio of older women to men: historical perspectives and cross-national comparisons https://pubmed.ncbi.nlm.nih.gov/10902048/ This paper seems to disagree heavily with you.
And extrapolating this to the middle ages and earlier:
In general, countries with a lower overall life expectancy had a lower number of women per 100 men aged 75+, while countries with higher overall life expectancy had a higher female to male ratio in this age group. A hundred years ago there were nearly equal numbers of women and men aged 75+ in many countries.
It doesn't seem to disagree with me at all.
