Not if you're using Stake Engine. No idea what they're referring to.
Making profit will depend how many people play your game, and how many people win big. You only get a cut of the profits, so if people are maxing your game often, you probably won't earn much.
I feel Stake is a bit misleading how easy it is for "anyone" to make a game though. You need a really, really solid understanding of Typescript (Javascript) to understand the code and create your own features, and you need a really solid understanding of how to create the assets. If you don't have experience in either of these things, you'll struggle even just asset swapping their sample games.
