I did the same thing (d/l to play with my niece) and was in the exact same boat as you at the start. Then I kept playing and improved a bunch. The building is still my weakest part but I am getting better and it’s safe to say I’m now addicted to the game I am playing it whenever I have free time.

It just takes practice, I started to get better once I went to low traffic drop points and loaded up on some good gear before getting into any 1v1’s now I feel comfortable dropping just about anywhere and only feel super anxious when I’m in top 10 and can’t build worth a damn.

I’ve had a bunch of top 3 and even came in second a few times and find that I’m killing myself in the end by getting caught by the storm or falling off of some crappy fort I built. Once you feel you’ve become a bit better try squads with random people and pick up on what they do, that’s where I’ve learnt the most when it comes to building.
