The fact that men skew slightly heavier and taller than women makes the strength difference even bigger on average. This is well known and well studied. Yes, it's possible that a woman at random will be stronger than a man . . . but it's unlikely.
I think we've been over all of the ramifications and interpretations several times now. Moreover, "unlikely" is imprecise, and your claim can't be evaluated unless you explain what you mean. Is "unlikely" less than 50%? Less than 25? Less than 10? It makes a difference, and it's already led to confusion in this thread.
In terms of upper body strength, I would estimate it to be approximately 5-10%. For lower body strength, maybe 10-20%.
The best hope for women to be stronger would be comparing a young fit woman to an elderly or disabled man.
An average male age 15-60 that participated in resistance training semi regularly can pretty easily be stronger than 99% of women barring any disabilities.
As an example - I’ve been to dozens of weight rooms all over the world, witnessing thousands of men and women exercising over the last decade. I can count on one hand how many times I’ve seen a woman bench press 135lbs. I was able to do that easily at 14 years old. I bench double that now for 6 reps.
Regarding leg strength, due to women’s build, they do have a somewhat closer chance of being stronger than men. I’d say that a woman who follows a nearly perfect strength training regimen for several years, can probably squat more than many men who do not exercise at all. For example, my wife can squat 225 lbs for a few reps, which is a ton for a female. This would be hard for most men that don’t workout. A man on an identical training regimen, however, could hit this much sooner with far more potential. I very rarely see women squat as much as my wife. I squat a lot more, and have never in my life seen a woman squat as much as I do, though through research some of the most elite women in the country can squat more. These are literally like 1 in a million women. That being said - I see men squat more than me in a weekly basis, as for a man, my squats really aren’t that spectacular.
Again - these are all my personal examples which seem to be far more extensive than any of the women disagreeing in this thread have mentioned. This is stretched between around 2000 workouts, several countries, and easily 30+ gyms in a dozen states.
I know there’s outliers, but genetics among genders all over the world are still relatively similar.
