I think the form of lottery I (and others) are referring to is the one where there are N unique tickets and you have a 1/N chance of matching those N numbers. Therefore, there is no dependence between different tickets and the likelihood of matching the winning numbers.

People will draw pictures, play birthdays, and attempt to choose layouts that "look random", none of which result in a uniform ticket distribution, which is what most people seem to mean when they say that something is "random". The takeaway is that "distributed uniformly at random" is not a great assumption at all when inputs are generated by a process. It's one of the relatively few things I did learn in my graduate algorithms class.
