I can't speak on the chances of a second draw but in relation to not many people here being chosen, as others have pointed out: In reality there isn't that many of us on here. Millions upon millions of people enter the lottery every year and of that, only 50,000+ get chosen (whatever the exact number is). Some have related this to a 1 in 100 chance of winning. We dont have 100 people on here posting that they entered the lotto so it's really not unusual that there isn't that many of us saying we won.
Myself and Jessica are from the OC which has a higher chance than most regions which would explain why there's two of us. You will probably see over the next few weeks more people popping up saying that they've won after they do some research and find the forum
