Is there a real, actually working way to earn money online without having a job?

Just wondering, as i am bored an curious because I'm in a position in life where i can get a job/cant travel to work. I remeber before I switched to lemmy and back when I used reddit, most people would promote their affiliate stuff or something, which really bothered me as it was quite common.

What legitimate ways are there to make money on the side from online without having a job? If you have questions, please leave a comment.
