The only way you could arrive at such a high figure is if you included transfer payments like Social Security and Medicare in "the cost to run the government", which is not how most people understand "the cost to run the government".

Social security and Medicare account for 36% of the Federal budget and are absolutely understood as a cost to run the government. Calling them transfer payments doesn't obviate the fact that they are costs to American taxpayers. Social security and Medicare are also the two Federal outlays that economists fear will bankrupt the United States.
