“I know many older girls who couldn’t get married if they had 100 boys to date”
Hard to believe since you aren’t a navi.
In any event there are most likely similar numbers of boys/girls who wouldn’t get married event if they had 100’s of dates. If anything there would be more males in that category than females-as the gemara attests.
