People talk about other people all the time - regardless of gender. I would guarantee they talked about male employees as well but your friend likely didn't mentally catalogue those discussions because they weren't relevant to her. Confirmation bias is very real. Maybe this one specific anecdote you're providing really was an example of rampant discrimination - I don't know - either way it certainly isn't indicative of the entirety of the industry. I could share many anecdotes of my own that I could interpret as people discriminating against me specifically - but I doubt that's the case. Instead it's people just being people. This is another issue, I think that these movement often make women and minorities attribute "normal" negative behavior to be explicitly driven by discrimination or x-ism rather than it just being par for the course.
