The odds for pulling a Serialized card from a random booster pack is generally advertised as less than 1%. Its difficult to find out more than that for your average set, but for the LotR set, we were given a little more information

Randomness is not a bad thing in a game and will add new dimensions as well as an element of fun however too much will make playing it pointless and frustrating

Drafts and Sealed events take a little longer though, so if your child is asking to start a Draft 10 minutes before bedtime, you may want to save that Draft for another time and back it up with screen time controls

Both plans are potent and need to be respected, and if your opponent doesnt respect one enough, they will lose to it
