Skills do have an impact on the game, but the cards themselves hold a big part of it as well.
In my perspective, there's 3 pieces that affect a game: You, your deck and your luck.
Knowing how to play, how to use your resources, keep card advantage, think 3 turns or more ahead, consider the odds of getting the card you need on your next draw, study your opponent's field, try to get inside his thoughts, detect his strategy before it pounces on you, all these things are needed to be a good player.
Your deck plays a role as well. You can play the meta decks and have bigger chances of winning out of knowing "the one trick" of the deck that is simply too powerful to ignore. For example, dracossack and big eye. Over and over. It's not too hard to figure out how to get them fast with dragon rulers, followed by extremely simple yet efficient effects, it makes for bigger chances of winning.
Lastly, if you have no luck and dogs pee on you all the time then you can't play worth shit. Even with a good deck and understanding of the game, if your luck sucks you will lose. It is a legitimate thing that most people don't consider.
So, in the end, archtypes are all different. Some stronger, some broken and some forgotten by the hand of the egyptian gods (who they, themselves, kinda suck in their playable versions), but a weaker archtype can definitely beat a broken one in the hands of a skillful player-- and with a dash of luck.
