I know many people that have cheap Android phones and never buy apps. I also know a few people (including myself) that own a top end Android device and buy a lot of apps (I have paid for 63 atm). Of course it not a rule (some people with lower end devices buy a lot of apps) but I think that is obvious that people with more money to spend on a phone are more prone to spend money on apps for the phone.
iPhone = premium device
Android = premium, medium and lower end devices.
