Yes, but Arale's Toon force is stronger/higher level than the Reality Machine's one, it has done more impressive stuff. Unless you want to tell me that Reality Machine's Toon force is stronger, there are levels of Toon force.
Also, Toon force power is not at all something that always the character know that it's using, at the end of the chapter, the characters were speculting what could have been the reason of as of why that happened suddenly to Beerus, so I wouldn't be too sure that it was cuz of the Reality Machine, that's what Trunks thought but he wasn't 100% sure and there isn't a true answer for this.
At the end of the day, she was saved by a gag plot, you know, the entire episodie was a Gag.
So this pretty much confirms that Goku's statement is a contradiction.
