Piano playing, reading music, and MT

Recently, I saw a post on here talking about how it is very important people hoping to get a BFA & be involved with MT in college take piano lessons and music theory. I have heard before that learning piano can be helpful to you, but right now I am not in the position where I would be able to take lessons. Plus, while I can read sheet music I’m not confident enough in my ability to put it into practice with an instrument yet. I have taken one introductory course in music and next year (Junior year) I am going to take Music Theory I and Electronic Orchestration as well as Chorus. Are you at a disadvantage if you can’t play piano, even if you are studying Music Theory?
