Do I have to compete if I horse ride?

I have been riding for a few years now (2-3) and I am practicing dressage, I have never been interested to compete and don’t like competing in anything, but my parents say that if I don’t wanna compete there is no point in spending money or time in horse riding, I love horse riding so much and want to lease a horse and we have thought about it but my parents think I should compete. What are your thoughts?
