The United States gets most of its petroleum from Canada.
Saudi Arabia accounts for only 7% of U.S. petroleum and crude oil imports.

2nd is Saudi Arabia then Russia. However it happens that US is also the largest consumer and their production doesn't meet the demand so they have to import from other countries like Canada and Saudi Arabia
So Saudi Arabia most definitely does have a lever, and so does Russia since the rest of the world including US allies like Japan, South Korea, Australia, NATO countries depend on their lovely black gold to have functioning economies.

Have you been following the news for the past two years? Russia's sanctioned up the wazoo. No NATO country is buying Russian oil. India is now their number one costumer.

If the US was like Saudi Arabia where they exported half of their oil, and could supply most of the world at competitive prices, Russia would have really felt the Sanctions.
But right now Russia doesn’t feel the Sanctions. They’re more isolated and Putin’s propaganda has somewhat worked at making the general population anti-west and support the Ukraine invasion.
