OP's original statement of "The death rate in the United States per 1000 male adults as of 2022 is 163." comes from [1]. That statistic is defined as, "Adult mortality rate, male, is the probability of dying between the ages of 15 and 60--that is, the probability of a 15-year-old male dying before reaching age 60, if subject to age-specific mortality rates of the specified year between those ages." [2]

And if you assume that death rate is age agnostic between 15 and 60 (it's not of course, but bear with me), then this allows you to calculate the yearly chance of death as a US male adult as 1 - ((1000 - 163) / 1000)^(1/(60 - 15 + 1)). This comes to 0.386%, or ~1 in 259.
