No, Anne Frank's story is completely exceptional - both in circumstances and the fact that she hid for so long (and her father survived).

This is a typical case of Survivorship bias. Most Holocaust victims left no memoirs (and no surviving relatives either), and did not even have their names recorded as they were murdered.

This is why just about everyone knows about Auschwitz which had a forced labor section and thus quite a few survivors, but few have heard of death factories like Sobibór, Treblinka, Bełżec, Chełmno, Maly Trostenets, Majdanek where survival rate was on the order 1:100,000.

Even fewer are aware that only about 50% of murders happened in the camps. East of the Molotov-Ribbentrop line people were mostly shot at random places (1, 2, 3, 4, 5, 6, &c &c), by Einsatzgruppen/Police Battalions/Wehrmacht/Local Collaborationists, not gassed in central facilities, and most of those places are still undiscovered.
