Yes, I remember seeing those posts on CC at the time. Another outlier. As I remember, that person was extraordinary and that OU program is extremely difficult to get into.
All this proves is that success is not impossible. Given the stats, it is, to use
@Goro's phrase, malpractice to give advice based on n=2. It's the equivalent of telling a high school kid with a great jump shot it's not necessary to focus on academics, because n=450 people with excellent jump shots make millions of dollars a year in the NBA.
Sure, it's possible, but most people with great jump shots and no education work in low wage jobs. Most applicants with zero gap years become reapplicants, even with n=2 extraordinary talents being successful (and I'm sure the actual number is far greater than 2, and far fewer than the number of unsuccessful applicants with less than 3 years of UG and no gap years).
