33 Million units at ~$20 is $660 million in revenue. This isn't including development costs, which are low for Minecraft but not zero (I'm guessing $5-$10 million over its lifetime.) Subtracting GTAV's combined development and marketing budget of $265 million still puts it ahead of Minecraft at $735 million, and it still has a lot more runway left.
Minecraft PC sales are almost exclusively Mojang's money (except for merchant fees) except when it comes to the giftcards that can be purchased in stores like Target. Minecraft Xbox is a licensed product so it's fairly safe to assume that Mojang are sharing a non-negligible portion of the revenue with Microsoft. Pocket Edition is sold through mobile stores and developed by Mojang.
The Mojang and Notch AB financial records are public -- as it is the way Sweden works -- by the way, if for whatever reason you want to look into the money that they're making.
