To be absolutely clear, every time some agency dismisses a Federal Employee, you’re not ‘saving money’. Each specific employee was a significant investment of funds, time and effort. They had to be cleared and vetted by the FBI and other agencies, at a cost of between 8-30 thousand dollars each. So »that investment gets smoked.

Additionally, though there’s ‘some’ fat in the system, the loss of function adds up quickly; those people are not just sitting there doing nothing of value. Think about dismissing 80% of your white blood cells, and you’ll quickly get the picture.
