If the last figure accurately represents the proportion who died while outside (vs when trees crushed their homes or cars), it would seem that those ~13 people a year in the US track lower than deaths due to lightning strikes [2].
Personally I’d rather not be out in a storm any more than I’d want to swim during lightning, but in absolute terms it does seem to be a healthy three orders of magnitude safer than being in a car in the US (at ~37K direct fatalities annually [3]).

Like statistics are a bad way to evaluate risk if the risk is easily avoided. Not many people die from swimming in lava; it is still wrong to conclude jumping into lava is safe.
Absolute terms of being in a car measured this way don't make sense.
People in the US are exposed to tens of billions of hours of driving annually and probably low millions of hours of being in bad storm conditions in forests. (I don't know, do 1 out of 300 of us even spend an hour in that?)
This is like saying that because few people die from playing Russian roulette, it's not too big of a concern to play now and then.
The response you've made has no probative value on the statement "Walking through a forest during a storm is an easy way to get hurt or die."
and who would film it?
