To say these people had pre-existing conditions, doesn't mean that this is what they died from. All you can really say is that people with those conditions might be more likely to die if they get coronavirus. In the U.S., about 75000 people are now dead, and if there had been no coronavirus, nearly all of them would still be alive.
Having rows of refrigerated trailers parked outside of NYC hospitals as temporary morgues isn't normal. It isn't something we have seen in past years. I don't recall ever having seen this, in fact.
One of the "pre-existing conditions" is just being older. If you are older than 60, for example. People I know in that demographic are taking this very seriously. Once you get to 70 or 80, the concern only grows.
A few anecdotes about deaths from drug overdoses or people being possibly incorrectly recorded as covid don't interest me. Anecdotes aren't a useful way to discuss this, and that just leads us down the path of comparing stories.
Another way to look at it is by considering "excess death". What this means is looking at the total number of people that died of all causes this year, and comparing it to what they would have expected (by comparing to previous years, for example):

In the article, they compare the official count of covid deaths to the number of excess deaths, and you can see that there is a significant undercount of covid deaths.
