I don't necessarily associate age with "noobishness", but I will state that I believe the younger generation is less likely to pick up an older Zelda game (in general). I will also go to say that the younger generation is less likely to fully appreciate (or even be able to appreciate) the older games. Why? Because, in general, the younger generation associates "good" games with graphics and mass character development. In general (yes, I'm going to keep saying "in general" because most people never pay attention to what I say and just skim through), the younger generation has been spoiled with newer games and think that an older game is no good because it's not up to par with what today's games have to offer.
That's not to say that many newer games aren't better. Lots are, but there are still many of the younger kids (and people new to gaming in general) who can't really appreciate old games like The Adventure of Link because they can only compare it to their experience with today's more updated graphics, music, character development, etc.
And then there is noobishness in comparison to others. When I hear "a REAL Zelda fan. OoT and MM type", I can't help but chuckle a little to myself. The Zelda franchise was around long before OoT, and just as it irks me a little to hear people who consider being an OoT-fan makes them an anti-noob, it'll one day irk today's "noob" Zelda fans when people consider TP a game to make them an anti-noob (if that makes any sense at all to you).
In any case, we were all noobs once. I hate that being a noob to Zelda is considered bad. Why? It's awesome to discover the Zelda series and fall in love with it. In fact, being a noob to Zelda is exciting! It's wonderful when you discover a series you really like and you can't wait to play all the others!
In any case, your age and how many Zelda games you've played.... it doesn't matter. Noob or veteran, being a Zelda fan is a great feeling. And hey, even the oldest of us turn to noobs when Zelda takes a new turn. How about when Zelda moved to motion controls or stylus controls? We all became noobs again in a sense, because we were completely new to that style of Zelda gaming. So, really, we all grow with Zelda, and whenever the series takes a leap into the new and unknown, we revert back to some level of noobishness, and I think that should be embraced and not ridiculed..
