Does computer games benefit me

Some, depending on which ones you play. Shooters won't benefit you in any way shape or form. But, constructive games, like strategy, puzzler and building games can. The only not-constructive games i play are racing games.

Also, games which allow you to script like: Minecraft (Mods) Blockland (More mods!) and Roblox (Actual games) can allow you to learn about scripting which will be a real benefit in your life if you want to be a games designer.

I'd just like to point out that Roblox is for kids and has a crap community. The good thing about it is how you can make full or proper scripted games that you fully made.
