You still didn't get the point. As I mentioned above, mostly only people care about the death of a better known person, when they were emotional connected to them, for probably over a half of their lifetime or even longer.
musicians that made you happy uncountable times with their creations. actors that made you laugh, cry, feel good or just let you feel any kind of strong emotional feelings etc. for many times.
one person likes that, the other person likes this. so it very depends on which what one will have stronger, lesser or almost zero emotional feelings when someone had passed away.
you see, many people really loved prin diana, so they sure got very emotional about her death, but which for me never was a big thing to worry or care about much, beside it was a tragedy just like many other face every day.
but on contrary, when a john barry, richard wright or goerge harrison passed away, I was emotionally shocked as if someone very close to me died, since they had accompanied me my whole life.
