I'm just curious, why do you think their machine learning algorithms are "shoddy"?
You type in gorillas and you get pictures of things that definitely aren't gorillas. The fact that it's highly offensive is just icing on the cake.
Likewise, job ads, ideally, would be shown to the best candidates, not necessarily the users most likely to click them... as you have speculated. HR is drowning in bullshit resumes as it is. Ads that produce more bullshit resumes from unqualified candidates who click/submit on everything will not be worth much to any company.
Without your pure speculation that the click through is what is driving the difference, all you're left with is an insinuation by the output of Google's algorithm that men are six times more likely than women to be good candidates for highly paid jobs... Which, again, simply isn't true and again, highly offensive.
