These numbers measure money: aid to Ukraine and the change in what Russia keeps from trade, against a world without the war. Weapons count at their money value: aid at market value when delivered, weapons and troops sent to Russia at the seller's gain where Russia paid and in full where it did not. Votes, diplomacy and intent are not in them.
