On the 17th of August, a large force of 376 bombers raided Schweinfurt and Regensburg. Sixty bombers, with six hundred aircrew, didn’t come back. 16 percent losses. At that rate, the Eighth Air Force could not continue. When B-17G’s began to arrive in August and September, the forward machine guns in their chin turrets helped a little. The appalling wastage continued:
September 6 - Over 400 bombers attacked the Stuttgart ball-bearing plant; 45 were lost.
October 14 - Schweinfurt again. 291 B-17’s went out; 60 went down.
January 11, 1944 - German aircraft industry targets. 600 Flying Fortresses were sent out. Because of bad weather, only 238 reached Germany; 60 were shot down.

I’d say the guy was exaggerating, but the reality was quite harsh enough. It is also possible he was including ALL bomber losses - American & British, both theaters and including training losses.
