Is it possible to hack into someone’s MySQL query browser?

There is a video game ( private server ), and i want to hack into that MySQL query browser, what MySQL query browser does in the video game that i’m playing, is basically where all the character data is located, level, class, money, stats, IGN etc….

I basically don’t know anything about hacking, but i read that you can hack into someone’s MySQL online Databases with Sqlmap. I’m a quick learner too.

But MySql Query browser is a program located inside your computer, it’s not a website thing.. so is it possible to hack into one if you only know the user’s website / IP ?
