How can things like worms and bacteria still be alive after being frozen in ice for thousands of years?

I heard a story about how a custom-made microwave emitter was used before the invention of microwave ovens for the scientific purpose of thawing out frozen gerbils, who came back to life from the process. They got so good at warming frozen gerbils from cryo, that they reached a basically 100% success rate.
The story said the reason it doesn’t work on humans is because of our large size. There simply isn’t enough time to thaw us out because we have to get more oxygen moving inside of us, and current technology can’t do it.
Otherwise, so long as not too many cells are punctured by the formation of ice crystals, some animals can do it. Chemical reactions slow to stand-still, and their state doesn’t change until heat arrives much later.
