Translating what FTC is saying to plain English, FTC is saying Epic didn't do enough to move liability away from them (Epic) and onto the parents/guardian. The liability ball was still in Epic's court, so FTC fined them.

If Epic had some form of age verification in place, past that point it's the parents'/guardian's problem whether the kid lies or the kid asks them to give their authorization. The liability ball would be in the parents'/guardian's court.

It's why all software and websites that handle data coming from underage kids always verify age or straight up don't handle that data (eg: Youtube Kids videos' comments, the lack thereof) at all.

Obligatory IANAL.

I’d recommend reading the complaint. To my surprise, regardless of the ratings, Epic was explicitly marketing to 10+. Like there are written statements to that effect.

> Epic was explicitly marketing to 10+

Translated to english this means they were marketing to 6-14 year olds.
