That's why I said that people will have "the opportunity to redeem at least 52 free games".
That said, Epic also has a habit of giving away two free games some weeks and they usually give away "X days of free games" around Christmas. It is very likely that people will get the chance to redeem a least 52 free games, even with repeats.
Who honestly cares how many potential games there is, if it's 52 or few less. You're getting free games, which you otherwise had to purchase. Just be happy they give it to you for free
