Australia is approaching 100 deaths and has several thousand confirmed cases through more widespread testing than new York, doing so at a higher and wider rate than New York who's stats/testing and medical regime show signs of severe failure/ problems.
Australia is yet to record a covid death under 40, and the one we have under 50 was technically a foreigner on a cruise ship.
All evidence from sources I'm familiar with that include widespread testing, good statistics and a healthy population point to a sub 0.2% for healthy young (young defined as sub 40 say, no comorbidities).
Now that being said, what I have seen repeatedly is a misclassification of sedentary young people with worrying lifestyle choices (think overweight/ smokers) as thinking of themselves as healthy with no comorbidities. Especially in some parts of the US, you can't think of yourself as healthy just because you live/look like everyone else.
And obviously, death rates in individual parts of the world will tend to be a function of age distribution, underlying health conditions, medical access, communication and the ability to rest and recuperate.
I personally wouldn't infect myself (the same way I wouldn't ride a motorcycle as my chosen mode of transport), but the relative risks and who the disease targets with mortalities should be better understood, and I'm not supportive of propaganda telling young people they're comparably at risk. They aren't.
It's a live updated page, so I don't know what stats will be displayed each day, but I'm relatively confident they will support my claim unless things change drastically.
You will find an infographic with breakdowns of positive diagnosis (known cases) and deaths. Both are helpfully split by age groups and gender.

Over 23,000 deaths and deaths under 30 have not even passed double digits yet. Only 1.1% of all deaths were people under 50; and that's deaths, not infected.
This is the most likely case for people how are not vulnerable, but by no means a sure thing. Plenty of people without preexisting conditions have died or had to be hospitalized for days or weeks.
Data is a bit difficult to filter, but as an example 4.5% of deaths in NY are from the 18-44 age group[1]. Presumably a large fraction of those were not vulnerable, or not aware that they were. The fatality rate in that group is somewhere between 0.2% and 0.4%. You are not likely to die, but those are not chances to take without a second thought.
