That's mostly from benefits, defense, unfunded tax cuts, and entitlements, not the type of spending DOGE claims to be addressing. Go look at a broad summary of Federal spending categories, then look at the history of the deficit under the last four or five Presidential administrations.

DOGE is about conducting an ideological party purge of the government bureaucracy. Overall I predict it will cost money, since it'll cause a lot of things to break and/or be replaced by more expensive contractors.
