It’s interesting isn’t it? “Guys” can include women, and can even be a group of only women, but you can’t talk about a single woman as a guy - “I snogged this gorgeous guy last night”.
Using “guys” for a group of only women works only in 2nd person. You can say “I love you guys!” to a group of women, but you can’t say “I was hanging out with the guys” when talking about the same group.
