it will be less odd in 20-30 years when the "celebrities" of this era start croaking.  The entertainment industry is so balkanized only a very small portion of the population will care when Jake Paul and Shia LeBouf die 
Most of the world will reply with,"Who"?  
It's only a phenomenon right now because a lot of the celebrities dying were uber popular in the 70's and 80's when the US had three TV channels and everyone watched the same movies at the drive in.  And American entertainment dominated global culture - even steelworkers in East Germany watched Full House broadcasts that leaked over from the West.
They would know who you were talking about that Danny Tanner died this year.  
No one in Poland today would have any idea who most the US tv stars are today. each show gets so few viewers compared to the old days
