With current sanctions, Russia can still earn money selling fuel to the EU, sure, but they have trouble spending it! They are already using more older missiles, having gone through the majority of their newer ones at the beginning of their invasion, when they thought it would be quick and easy. They do have thousands of missiles left, although mostly the older, smaller ones as far as anyone can tell, and it's not easy for them to replace any of them.
