Per the referenced link, of the 35 serious incidents between 1983 and 2017, there were 3,823 aircraft occupants. In that group, if you either survived or died from smoke/fire, there is a 7.2% chance you died from smoke/fire.

I can't fine tune that number to determine you survived the crash, but then died from smoke or fire, since it did not easily differentiate pre-crash and post-crash fires.

I am not sure I would agree or disagree that it is usual to die from smoke inhalation after surviving a plane crash given the reason that people took too long to evacuate. It just feels like the upper limit of how many people die that way can't be that large since many of those smoke/fire deaths would not be attributable to that cause.
