How to make money online

Hi everyone! I'm wondering how I can make money online. I don't have any money and I don't want to ask my parents, as I'm already 18 and don't want to bother them, and we're currently having some money problems. Any options? I've been wanting to start trading, but I don't know what to do. I've watched dozens of videos, but I still don't understand how it works. If anyone knows anything about this, I'd like to ask if you could help me or suggest another way to earn money. Thanks in advance. I'd be very grateful to everyone who responded to this post.
