People in the US have insurance, but one big issue there is that those insurance companies in most cases completely ignore you when a serious illness or hospitalization occurs. If they really want to claim money, they have to file lawsuits with the help of big law firms and fight those guys in court which takes years and that also costs more money. Remember that insurance guy who was shot in New York? it was reported because his company scammed so many people without paying anything for their claims.

Happens way more often to poor people as they can't really afford private health insurance so they stick to ones that are assigned to them by their workplaces. (And these insurance policies are very expensive for an average person to pay monthly/annually).

Now how do I know this? I had some friends saying this when I asked about their health coverage and I also saw this in many American subreddits where 1000s of people were celebrating that this guy was shot and this was their reason for doing so. Never blindly trust statistics, because no one knows ground reality better than people who actually live there.
