In playing this Game, Players acknowledge that it is a game of chance, that the outcome of a Play in the Game is pre-determined by the Interactive System at the point of purchase, and that the winning of a Prize in the Game does not involve the exercise of any skill or judgement by a Player.

That part is almost certainly to comply with gambling licencing laws. There are different laws if it's a game of chance or luck. That's why many raffles (a game of chance) have a really simple question at the end, to turn it into a game of skill, legally.
