Are those prediction apps for games actually worth paying for?

I've been seeing a lot of ads lately for these apps that claim to predict outcomes in certain online games. They promise higher win rates and all sorts of fancy features. I'm always skeptical of these kinds of things. It feels like those "get rich quick" schemes you see everywhere. Has anyone actually paid for one of these and found it to be worth the money? Or is it just another way for companies to take advantage of people hoping to get lucky? I'm curious to hear if anyone has any real-world experience with them before I even consider trying one. It seems too good to be true, honestly.
