it definitely shows a gap in employment for higher-paying jobs, but that's not active discrimination as much as it is gender roles doing what they do
There's definitely a much higher amount of loveual discrimination in the extremely high up positions like board of directors, CSO, CEO, etc. And this can be plainly seen as over 80% of the top 1% of americans (which control almost half of the money in america) are men. I'm all but certain that that's where the majority of the original 20-23% figure comes from in the first place. Thankfully, that statistic is improving more and more each year.
