We have a lot higher % of older people, and the older people who live in India that could have been killed by a single illness are probably already gone with all the trash, sewage, and biological contaminants affecting their water supply.

But still, as you aid, the numbers are almost certainly wrong. US numbers are inflated by false positives, counting "looks like the symptoms of COVID" as coronovirus deaths, and counting any death where coronovirus was present as a coronovirus death. Meanwhile I can't imagine a relatively impoverished country like India is doing much testing compared to countries like the US, so if an elderly person gets sick and dies, I wouldn't be surprised if it's often not counted - since you know, that's what tends to happen to elderly people.
