Hey there!
Oligarchy is rule by the rich, usually aristocrats. They indeed did not get their money in an honest way. In most oligarchies, they made laws that benefitted themselves, like unfair tax and odd charges. A common outcome of this type of government is making the rich richer and the poor poorer.
