Is it hard for women to become an airline pilot?

I am a student pilot in high school and is deciding where to go to college. I am not having a big support from my parents on being a pilot. They think I am a girl and it will be hard for me to compete with guys when I apply for an airline job. Moreover, I am only 5’1 feet tall.

Is it true that airlines will consider guys first when they hire pilots? and will the airlines still hire lots of pilots by the time I graduate from college(4 yrs later) ?
