I want to get a role in the musical Wicked one day but my classmate criticized me and said IF I get an audition and I feel discourage. What do I do?

I want to be in the play Wicked but my friend from drama club in high school said, "That is IF you GET in audition. You gotta have talent and the experience besides school plays. If you show them your resume of your school plays, that means NOTHING to them! You gotta do more than that, including community theatre and all that. You're not going to get the part with just weak high school plays! LMAO. I'm just being real. You gotta be realistic. That's not going to mean a damn thing to them."
Wow that really hurt and discouraging. I want to be in the okay. I've done 14 school plays. 2 each on the three years of high school. I start senior year next Monday.
