Arguing their capital ships and the cream of their officer corps is gone would be accurate. But you'd have numerous light patrol craft and probably thousands of starfighters stationed everywhere, and significant retried/reserved/training officers in the rest of the Galaxy. And, as part of their attempt to make sure the New Repiblic was small enough to be wiped out, significant numbers of world's both in and outside of the New Republic were pushing for decentralization because they feared a centralized autocracy... Which means that logically, on some level, they'd pursue planetary and system scale security forces themselves. Again, nothing big enough to qualify as a ship-of-the-line, but you'd have significant forces still in the game.
And politically speaking, the idea of a Galaxy rolling over after TFA is laughable; there's whole species, planets, and populations that will know that they're probably targeted for slavery or genocide under a New Empire, so you're going to see the Mon Cala, the Wookies, the Twi-leks, Chandrila, and all remaining Alderanian descendants arrayed against the First Order. Or you *should.* And that's not taking into account that political nations have enough inertia to survive most decapitation attacks, especially against a foreign power-- unless they are directly occupied by an opponent, which brings us into our next problem.
The First Order was not *technically* in a Cold War with the New Republic until 5 years ago... Because even in the TLJ-friendly material, the original Imperial Remnant they were formed from was hidden in total seclusion within the Unknown Regions, only gaining their main Galaxy foothold when the Centrist planets seceded from the Republic 5 years ago. The Unknown Regions First Order force is still supposed to be formed from a hidden section of Imperial military forces that disappeared there, and the main Galaxy portion is still supposed to have had to engage in its arms race with the New Republic in secrecy (this is why Poe is shown shocked at the size of the Star Destroyer hangar in TFA).
The issue, lore wise, is that this means that even in Johnson's customized Galactic set-up, the First Order has access only to the resources of a territory forged from a minority party breaking from a not-quite Galactic Republic combined with the logically still new and only-so-many-planets-they-can-occupy-and-man in the Unknown regions with strictly a military force for 30 years. Don't get me wrong; it's still huge... But it's not "Monopoly on manpower and resources owned by a Galactic Empire formed from the military forces required to win a Galactic scale false flag war" huge. And we know that was still just barely enough to hold onto the Empire for a year after Palpatine died.
So... Either the film is badly written because it expects us to accept an implausible scenario wherein the Republic is truly wiped out after one attack and the First Order has Imperial-sized resources because they were too lazy to use logic for a more interesting scenario... Or the film is badly written in comparison to TFA because we are seeing the *bulk* of First Order forces here, and these written-to-be-more-incompetent idiots in this film wasted half their resources because they couldn't pursue or cut off antique equipment and because no one in Star Wars history has ever tried a hyperspace ram.
Which is why it's a shame Johnson didn't follow Abrams and the Story Group's attempt to make the First Order a smaller, leaner, but sharper and more efficient antagonist in TFA. *That* would have been new and interesting.
