If you're looking to make sense of it all without getting overwhelmed, one place helped me a lot. I randomly came across https://dmarket.com/cs2-wiki/ while reading a Reddit thread on skin wear levels. It's actually structured well — they explain things like trade-ups, rarity, and skin wear in a way that doesn’t make you feel lost. I didn’t even plan to trade at first, but now I’ve done a few safe swaps and learned what to avoid.
