If they have to get it by rolling a slot machine, they can put in quite a lot of money before they finally get it. If there's a fixed price on it, the developers are effectively capping how much money they can make. The goal of these games is precisely to get you frustrated enough with the RNG that you spend money. It's frustrating, but that's just how the business model works.
