~30,000 skiers and hikers annually makes that rather misleading. Consider, NYC has vastly more deaths, but it's not particularly dangerous.

Sheer volume is meaningless unless we know how many times it's been successfully summitted. Mont Blanc is dangerous because it's easily accessible to lay people and despite being advertised as a 'long walk' can turn deadly very quickly.

Annapurna on the other hand has been climbed less than two hundred times in history, all of those people were elite mountaineers and further third of them didn't make it back.

Denali is pretty bad as well.
