The idea is to compare the risk of death from the AZ vaccine from blood clots (1 in a million so far) with the risks we take all the time without worrying.
For there J+J vaccine, it's also a 1 in a million risk, but just of getting the clots, not dying.
The point is to show the fallacy of comparing the risk of the vaccine with a perceived current zero risk - you are not at zero risk ever, there's a base-risk we as society and individuals have decided we are OK with, because without it we can't even get out of bed in the morning, let alone get into a car or do anything else interesting, and the risk from these vaccines is a lot lower than that.
