How to make money with airdrop?

I'm curious about the concept of airdrops in the cryptocurrency world. Could you please explain how someone can actually make money through this mechanism? I've heard rumors about free tokens being distributed to wallet addresses, but I'm not entirely sure how it all works. Are there specific steps I need to follow? Are there any risks involved? Also, is it realistic to expect significant earnings from airdrops, or is it more of a fun and exciting way to get involved in the crypto community? I'd appreciate it if you could break it down for me in a way that's easy to understand.
