You have to multiply by the respective probabilities of both of these things happening to arrive at the expected number of deaths. 0.01*(35/97) would be significantly bigger than 0.000001*(97/97), as a hypothetical example.
That said, planes have had years of safety R&D which helps get that number down to 0.000001, and maybe the same could have been done with blimps if they were given the opportunity?
The Graf Zeppelin, one of the Hindenburg's contemporaries, flew regularly accross the Atlantic, flew into the Arctic Circle and exchanged mail with a ship there, was the first vehicle to fly around the world and set a round the world speed record, was the first vehicle to cross a million miles flown, did 590 flights, carried 34,000 passengers, and did so with no harmful accidents and no fatalities, despite losing four engines on one flight and needing a forced landing.
Yes I imagine something similar could have been done in the last 70 years if they'd kept being built en-masse.
