doubt it. I've been playing casually for a couple months tops, (maybe once or twice a week, and even less recently) and I went to my first, got totally crushed, but learned a lot and got to play a lot. The overall smash community is a very friendly one, and I think it's because everyone was once in that position.
As it's been stated multiple times, going to tournaments is a great way to learn, especially if you can get in a lot of friendlies, IMO because it forces you to learn a bit more of how people play, and that in itself opens up a lot. For example, I can play against my friends over and over again, but after a while you become accustomed to their playing style, and if you've never gone to tournies before, you'll realize quickly that there are many other ways of playing, and from that your knowledge increases (bleh... been repeating myself forever, I tend to do that)
tl;dr... go to tournies and play friendlies if you can
