Hello there!
There is quite a HUGE difference between these both. When being frauded or making a fraud, this would also be known as stealing money.
But when making a mistake in a statement, they can be things resolved faster than if a person were to steal money. When making this mistake, you could resolve this by explaining why this was a mistake and also what could you do to fix it as well.
Both of these kind of acts are seriously two major different things, they have nothing in common.
