Information about Arizona State?

Ok, so I was doing my research on the W.P. Carey school of business at Arizona State University. I saw that Arizona State University is not a hard school to get into but their undergrad business program has just greater than a 20% acceptance rate. What does this mean? Will I have a hard time getting into their business program because the acceptance rate for W.P. Carey is less than 30%? Answers please! (FYI I am still a high school sophomore that is seeking information about ASU as well as their business program)
