No they are not. YC has more experience than you. YC has more success than you. If they turned you down, listen to the "why" and make the adjustments necessary to be successful. Consider it a badge of honor that they even gave you the time of day. Take the information, feedback, advice, and rejection to heart and grow a pair. Success is not static, it is dynamic.
