You can worry about all that stuff and yet still indulge with your hobby.
It might not be as much as it used to be in the younger days but still possible.
Like right now I play games during work days (Mon - Fri) at least 1 hour when I am at home (PS3, PS4, Xbox Series S, Switch or PC).
I get an extra hour at work due to a 1 hour lunch break - so I get out a portable gaming device I own (Switch, 3DS, PSP, iPhone, etc).
During weekends and holidays I might get 2-3 hours unless I'm spending time with the family during outings, etc.
That is more than enough time especially if you juggle between 2-3 games. (I'm juggling between 10-12 games lol)
