Three girls by Amrita Sher-Gill

I was always told to check in the dictionary for meaning of words I never understood and therefore I did when I wanted to check what exactly a woman means;

“an adult human female” so why do people always keep saying that a woman is a person who makes sacrifices, who is simple, who is decent, who has no right to speak up or object, who is gullible, who needs to be protected, who is as resilient as water, who is not supposed to take decisions……….
to which I wonder is my dictionary wrong or am I on the wrong page?
