Not necessarily. It could be the case that randomness plays a huge part in non-environmental caused deaths, and if that were the case we would see very little heritability.

But randomness comes from the environment, no?
No, you randomly get cancer since cancerous mutations happens randomly. Environment can just affect chance of getting cancer, it doesn't give you cancer directly and there is no way to completely avoid cancer risk.
For example even if you live the best life possible you will still have an inherent cancer risk based on your genes and that affects the random chance of you getting cancer, it isn't a clock that says exactly when cancer will happen.
Technically, sure, but that doesn’t mean it is related to anything observable about your environment.
