Elephant lifespan

I am currently debating someone on a casual geographic reaction comment section about elephants in zoos. He claims that over 150 and more have died prematurely in zoos as of recent, which I know it’s been stated for a while elephants are one of the few animals in zoos that do worse, but when I began volunteering at zoo Atlanta years ago as a teen, I can remember during a training a keeper telling us recent studies are showing elephants live about as long in zoos as they do in the wild now as care has majorly improved. Can anyone who works with elephants or a zoo with them (as I currently don’t) chime in on this?
