I want to propose a different hypothesis - men and women lie differently. Men are more likely to say they got no matches on a dating site and complain whereas women are more likely to keep quiet of they get few to no matches and exaggerate the number they do get.
Maybe men are more likely to blame the site or algorithm whereas women are more likely to blame themselves.
Maybe ratios of unsuccessful attempts are roughly evenly distributed and the difference can be explained solely by the fact that men must ask and make the first move in most cultures whereas women don't have to.
