Of course your newbie head is spinning- us oldies heads spin watching that caliber of athlete too. The best of the best go to Worlds- it's the Olympics of the years that aren't quadrennial.
You can go out and learn a lot of that stuff spokes, and though you may not make it to Worlds having a lot of that swell technique will raise your fun factor a lot! Ride hard and regularly and you too can zoom over hills. Go look at the racing club training rides, those guys live in your town and have high seats and low bars. It's not as distant as you think.
The novice period in most sports averages two years if you play a few times a week. You grow muscle and aerobic capacity, learn technique, accumulate better gear and an understanding of what it does. Think of it as an adventure; you'll get better and will start to argue over race highlights like a middle aged European guy. But look MUCH better in short skirts. And this is even if you toodle around.
Just wait 'till you watch Le Tour next summer! Almost a month of same.
