Relying on predictions to bet is much riskier than simply betting. Promoting affiliate links is an economic activity encouraged by casinos.
They encourage it because they benefit from it directly. They are paying people to refer their casinos or spread their brand so that they can earn more from gamblers who go to their platform.
The only one who wins when you lose is the casino itself. “Influencers or affiliates” have no reason to deceive you with false predictions, as this will cause them to lose credibility and, as a consequence, lose your referrals.
It will only be reasonable for an influencer to provide false predictions if they plan to scam you for one time. If they wanted to make an actual business of predictions then they need to build a good reputation
