I learned that it is referring to how women are zoche to Techiyas Hamaisim specifically.
There is a specific merit to supporting men’s learning, but women do get schar for their own learning even if it’s not the same thing. The Rambam says that women receive schar for learning Torah. It’s like any other Mitzvah that women do that they aren’t obligated to do but they do as “aino metzuveh v’oshe”. For that matter, they aren’t chayiv to get married in the first place.
According to the Maharal, women don’t have a chiyuv to learn Torah since they can get Olam Haba without it.
