Not really. I've seen more than one microservice-architected (admittedly, poorly) systems where, instead of the whole DB freezing up, just the one DB would freeze, but then all of the other microservices that talked to the frozen microservice didn't correctly handle the error responses, so now you had corruption strewn over multiple databases and services.

So, while true the failure mode would be different, "one bad query fucking up your entire system" is just as possible with microservices.
