It does not cut individual benefits that citizens receive, but instead targets waste and fraud in the agencies themselves.
Its an overall budget. That also takes into account the projected savings under those same agencies.

Trump’s 2020 budget to reduce Medicare costs by targeting waste, fraud
President Trump’s budget would largely skip the hard work of cutting entitlement spending, the biggest driver of federal debt, instead proposing to slow the growth of payments to Medicare providers and leaving Social Security untouched.
Total spending on Medicare in Mr. Trump’s proposed fiscal 2020 budget would rise from $645 billion currently to $1.2 trillion in 2029. But administration officials said it would reduce projected Medicare increases by $845 billion over 10 years, about half by eliminating waste and fraud, and by lowering the prices the government pays for prescription drugs.
Russ Vought, acting director of the Office of Management and Budget, said Mr. Trump is “keeping his commitment to America’s seniors, by not making changes to Medicare and Social Security.”
But Democrats seized Monday on the president’s relatively modest entitlement proposals as a 2020 campaign issue, accusing him of breaking his campaign promise by “cutting” Medicare and Medicaid and abandoning seniors.
“This budget does the exact opposite of what Trump promised the American people,” said Sen. Bernard Sanders of Vermont, a contender for the 2020 Democratic presidential nomination.
