Yes it is true that a scratch can theoretically turn someone. Kate asks Chris Argent about it during a Lacrosse game when they suspect Jackson to be the beta. Chris said it is possible if the scratch goes deep enough It actually happened to Kate when Peter ripped out her throat, eventhough she became a werejaguar and not a werewolf. Peter actually intented to kill her. Maybe that's it?

It's hard to say since we have a very Little Information. What do we know? When bitten by an Alpha, a human has to possible outcomes, he either dies or becomes a werewolf (or something else Kanima, Werejaguar etc...). A scratch, when deep enough, can also turn you. Maybe Deucalion never intended to kill Braeden? The scratch definately didn't go deep enough.
