Not true in the slightest, especially in the upper body region, which would concern swordsmanship in particular. Men are about 50% (or 1.5x) stronger than women in the upper body, and the difference between sexes in grip strength is probably the most extreme. Again, both pertainent to swordsmanship.
Not many women in 100 (if any, numerically) would be stronger than an average man.
Not to meaning revel in any of this. It's just the way the human body differs between the two sexes.
