My view is that it's bad math(s).
Gender pay disparity has a lot of causes. Some of it is no doubt discrimination, some of it is no doubt not discrimination. Don't lump it together and call it all discrimination.
These affect workplace earnings: education, experience/time in workforce, career pursued, discrimination. Some of these can be affected by a woman's desire to parent her children, if she exits the workforce to do so. Or if she picks a career (teaching*) that more aptly fits her needs as a mother than other professions (lawyer/barrister*).
Comparing like to like (apples to apples or plumbers to plumbers) will provide interesting and useful data. Looking at average weekly earnings is neither interesting nor useful.
*in US 76% of public teachers are female, roughly 45% of lawyers are female (although many more females exit the labor force; lawyers make more than teachers, so on average men will make more than women when comparing all educators and lawyers. While discrimination may exist in these industries, the fact that average earnings is different does not suggest discrimination.
More from the 2nd linked article:
You're looking for the wrong thing from the stat. It's an indicator of a problem, not a statistical certainty of one.
I'll clarify - I'm not saying ALL of that 20% pay differential is due to gender discrimination, but what I am saying is that for such a large gap to exist then it is very indicative that a problem exists, because it's simply too large to be anything but a problem.
To draw a parallel, black Americans are far more likely to commit a multitude of crimes, despite being 12% of the population. A lot of that will be down to comparative living standards, education and so on, but there's also an element of racism in play that boosts those numbers. We'll never know for sure how big a factor racism is, as it isn't a defined stat, but you can use common sense and realise the stats are just too disproportionate to not be impacted by it.
And again, looking at common sense, you only have to look at the world around you to see that gender discrimination in employment is a massive thing. How many females do you see on tills in supermarkets compared to men? How many male MPs do you see compared to women? You talk about the legal profession - only 25% of judges are women. Under 13% are architects. Time and time again you'll see jobs that women could do as well as men, consistently overlooked in the profession, with the gap simply too big to ignore often the only common comparison on offer - gender.
