No I do think its possible this time though the maths behind it is funny perhaps. If 3 million people take part in this promotion and they get say 2 Golden ticket and maybe they already have 2 or 3 themselves just from normal use of the site in some way and GT win on wheel spins maybe. So collectively thats perhaps 9 million GT tickets and the result of the draw could result in someone with very few tickets winning not as they alone had a great chance but because multiple instances of this outcome were entered into the draw.
We may end up seeing 'the little guy' winning this one and its justifiably a possibility.
