Affiliate marketing is actually hard to do my dear but from what hear about how it works it seems that people are really cashing out good time from it because most of the online content creators an skit markers are fully involving themselves into affiliate marketing, that is why we finds most of them doing some promotion on some gambling site saying 'to sign up click on their link and or even use their promo code for bonuses' this shows that are doing affiliate marketing. From what I read @Davidvictorson has already given the full meaning and nothing much to explained over there.
You will only earn good money from commissions if you have enough affiliates under your account. If you are not good in getting those people to use your affiliate link, and if your affiliates are not very active in gambling, you won't also get good money out of it.
How it works have been explained already, now, what you need is think of how you can get those affiliates that will use your link.
Are you a people person or an introvert one? This will determine how well you are in approaching potential affiliates, whether in physical or online platform.
Popular influencers/streamers can earn good money out of this because some of their subscribers really spend money to play or follow what they are doing. But of course, they don't care if their followers are earning or not to what they are saying. They usually are concerned on their public image or how they portray themselves oncam to get more audience and subscribers.
