ofc not, but in my opinion a very large amount do.
One thing is making your life out of it, that requires you to spend a lot of time doing so, other thing is playing just to pass time and waste most of your life with a useless hobby.
It is knwon that it helps develop some skills but those skills are rarely used in real life use cases.

Gaming is not the course it is the tool . Same addiction is seen with many things , social media , some sports , popstar fandom , just name it .
The problem lies deeper .
I had a lot of profit in live from my game skills , reaction time saved me many times in real live , as a gamer you train that . I became Laser programmer/opperator cause gaming on pc learned me a lot . ( try to run Black ops 2 on a Atlon II and still be someone online ) .
A negative point of view will not make you see the bright sides .

Blaming gaming is to easy , look deeper .
