This is absolutely not true at all. Wireframing is nice and can be important, but it's not design, it's architecture. It tells you the ballpark of what you might want to achieve and how a app/site might be structured. You need to sit down and put real-world pixels to the screen to see if the thing you're making works and fits. Rendering is not fashion. It's every bit as much function as the code on which an app/site sits. No wireframe tool I've ever seen will let you know how much text you can or should fit on a particular sized canvas.
