The most recent CDC numbers indicate that 80% of the deaths attributed to COVID-19 are in people 65 and over. When you lower that to age 55, it become 92%. 45 and above, 97%.
This is not a black plague that's killing millions of young and/or healthy people. Like other respiratory related viruses...the old and compromised are the most vulnerable. I'm not saying "It's just the flu", but the statistical breakdown is quite similar. I've had this discussion with a good friend who's an epidemiologist and that's her take as well.

*Note that there's a reporting lag on this CDC site, these are "confirmed" deaths. So the overall number is below current estimates you hear. But the breakdown by age is pretty constant.
