ICBMs are spaceflight rockets, imo it’s best to count them. The US hasn’t had such large accidents with ICBMs, mostly minor ones.
Even if we exclude those it’s not true. The US has sent significantly more people into space than the Soviets did, so NASAs accident rate was lower (hence safer), even if the absolute number of deaths was higher.
