No, they don't. People shouldn't worry too much about trying to achieve something on games. When people do this they will tend to stop taking care of themselves in small ways... Like staying up later, then being tired for work.

What I'm trying to point out to you is people who boost, probably have lives. They just don't have time to earn it normally. But it could be the other way around... And also it depends on how you use the word "life." As in they need to get a life by stop boosting or they need to get a life outside of gaming and enjoy it the way it was meant to be which is the right way. (Not trying to start an argument or get off topic).
