According to me, it depends on the type of came one's playing, but I don't agree much on it.....
Although there are few games which does help a bit, but believing that playing games like Call of Duty, or like Genshin Impact, is totally absurd, according to me. Concentration can achieved via playing physical games as well, and that will be even better because it also develops overall coordination of the body.
Playing video games may help in quick eye movements and reflex of our hands, but concentration is mostly referred for least deviation. So one's better looking at a particular point, or flame of candle to improve concentration, than with playing games like those which I said.
And not to forget that those games also affect at mental level, when people tend to attracted to those imaginative worlds.
