You can tell that being rejected by YC isn't that strong indicator for success given the number of YC startups who have been public about having only got into YC in their third or even fourth attempt. In my book that is equivalent to being rejected, and YC only accepted them after they basically made it.
YC is also very public that a significant number of every batch have been rejected a couple of times. So basically being rejected by YC is not even a strong indicator that you won't be a YC success.
