"Really good" is subjective. It's the very notion something is possible and that you can do it that I see as valuable. Practice makes perfect, nothing can be perfect the first time you learn it.
To summarize for those who can't/don't want to watch both videos: Just because world renowned chef Jacques Pepin makes an omelet look easy, doesn't mean it is.
My experience was that it made me look at omelette cooking in a totally new light. My omelettes aren't perfect, but I actually like them now. And my wife (who loves them) approves of the new technique. (I use cast iron and don't get the exact results, but they are greatly improved)
This video with Gordon Ramsay is just as good. These two videos together will teach you basically everything you need to make scrambled eggs and omelettes.
Pepin himself starts out his video by saying that the omelet is the dish that he would judge a chef by, implying that it demonstrates all of the skills of the chef. I'm not sure how this is supposed to demonstrate that you can learn to cook in an hour.
I wouldn't say "learn to cook in an hour", but I would say it gives you the confidence that you /can/ cook, and even learn to make just one thing good enough for just you. (an actual achievable goal)
