It could be that I am misunderstanding that infographic, but it appears only to count deaths from the actual blasts and possibly from fatal short-term radiation poisoning. It does not appear to include subsequent deaths due to starvation and economic collapse.
I believe your interpretation is correct. I find it hard to believe, though, that everyone would die in the event of an economic collapse (even economic collapse plus nuclear winter), though it seems very likely most would.
This is the source that changed my mind, although it appears to be somewhat controversial.
Is the “complete destruction radius” the same as the “everybody dies in this radius”?
I am not an expert in the nuclear weapons business, and so the best I can give you is “>50% chance?”.
