Based on what Convergence said everything from Pre-Crisis on exists.

So you have the Pre-Crisis, Zero Hour/Hypertime multiverse, 52, and New-52 multiverses all existing. As nears I can tell the hierarchy is something like this:

Zero Hour/Hypertime multiverse Pre-Crisis multiverse Post-Crisis multiverse 52 multiverse New Earth New 52 multiverse

Just as DC moved from the Golden age to Flux to Silver age Earth without telling anyone we moved from a Pre-Crisis "Earth-One" to a "Earth-One-Beta" where Crisis happened.

With each "reboot" and Crisis we have actually moved to a different Earth in a different part of the DC multiverse.

It's a "scale" of infinities: Vsauce's The Banach–Tarski Paradox explains it.

To over simplify there are more points between 0 and 1 in fractions then the infinite set of countable numbers.

It would be if you had an infinite amount of fruit and only removed the grapes; you would still have an infinite amount of apples, bananas, and you get the idea.

This is basically what the anti-monitor did: yes he destroyed an infinite number of earths but they were only a sub set of a larger infinity.
