Isn't the cost of the ingredients some $0.2 (I have no idea, just estimating by the taste), so that machine is printing money when working?

It's surprising they cannot build a machine that does not break that easily.

I wouldn't be so sure. Milk, cream, and sugar are relatively expensive ingredients, and labor is very expensive.

Milk/cream is not cheap. It takes a lot of energy to freeze that mixture as well. Most people don't try to measure this, but the ice in your soda probably costs more than the rest of the sugar water (in bulk/wholesale as restaurants buy soda, if you pay retails prices things are different)
