You weren't hacked, you were careless with your data. This is a game ban, by the way.
It doesn't matter who used the cheats; the affected account will be punished.

Counter-Strike 2 game bans are permanent, non-negotiable, and cannot be removed by Steam Support.

como eu fui descuidado com os dados, sendo que eu tenho steam guard, o cara que jogou na minha conta era literalmente de outro continente, porque nao seria revisado, a valve nao estao nem ai para os jogadores?

You can't have been hacked, because even Steam only stores your password as a HASH.
So if you don't protect your data, Steam Guard won't help you either.

Valve offers you hints, tips, information, Steam Guard, etc. They do more than enough to keep users' accounts secure.

I see you're in some skin trading/gambling groups, you likely got phished from one of them.
You're expected to know how to keep your account safe. If someone else was using it, you are responsible for anything they do with it.

Quando você entra com suas credenciais do Steam em sites de terceiros, você autoriza o uso de sua conta. Isso é descuido. Antes que você diga que não entra nestes sites, você participa de vários grupos deles, assim provavelmente entra.
Abra outra conta e use suas credenciais do Steam apenas no Steam.
