BS. Russia did not achieve a 5-to-1 artillery fire advantage while the US was actively supplying Ukraine. Russia achieved that, and perhaps more, only now, months after US stopped sending ammo. Artillery fire rates were about even earlier, and would be again, if US provided aid Vance votes against.

Odds are getting worse thanks to him and his cohort, specifically.

Absurd strawman. No one says the US should prolong the Ukraine war in an attempt to yield economic gain. Many, however, argue that Ukraine aid is great cost-benefit in part because the US isn't burning money, it's paying US companies. Most likely Vance knows this and it's just a bad faith argument.
