I'm saying the source that you cited says that the 3.4% figure that you cherry-picked is disputed.
"... public-health scientists say the real death rate is probably lower than the current estimates. U.S. health officials suggested in another article in the New England Journal of Medicine that the death rate could be well below 1%. (Other estimates have ranged between 1% and 2%.) That’s because current calculations are based on tallies of people who were ill enough to be tested, they wrote.

Tell it to the World Health Organization, you FUCKING idiot.

3.4% Mortality Rate estimate by the World Health Organization (WHO) as of March 3
In his opening remarks at the March 3 media briefing on Covid-19, WHO Director-General Dr Tedros Adhanom Ghebreyesus stated:
“Globally, about 3.4% of reported COVID-19 cases have died. By comparison, seasonal flu generally kills far fewer than 1% of those infected.” [13]
Initial estimate was 2%
Initially, the World Health Organization (WHO) had mentioned 2% as a mortality rate estimate in a press conference on Wednesday, January 29 [1][2] and again on February 10. However, on January 29 WHO specified that this was a very early and provisional estimate that might have changed. Surveillance was increasing, within China but also globally, but at the time it was said that:
We don't know how many were infected ("When you look at how many people have died, you need to look at how many people where infected, and right now we don't know that number. So it is early to put a percentage on that."[1][2]).
The only number currently known is how many people have died out of those who have been reported to the WHO.
It is therefore very early to make any conclusive statements about what the overall mortality rate will be for the novel coronavirus, according to the World Health Organization [1][2].
