You know, words have meaning. The term "correlation" has a meaning that is very well defined. You said "cases don't mean deaths. There's no correlation.". This is obviously false, as we can see by looking for a time before there were any cases and seeing that, lo, there were also no deaths.
What I think you're trying to say is that you think covid19 infections and deaths are not linearly correlated. That is true, but I don't think anyone ever has ever claimed that they were. What is is however true is that covid19 infections and deaths are positively correlated. Which means that deaths tend to go up when cases go up, and go down when cases go down. The amount of correlation varies for all sorts of factors (demographics, medical care etc).
