I disagree with you . It all depends upon the number of visa available. So, your 2nd point is right though, but at that stage of the game you generally get an idea of if you will get the visa or not. So, I guess you are tying to scare the winners by saying these things, or probably you have won DV lottery with case number at the end,and you are less likely to get the visa if people before you put in their families. Remember , the number of visa available is fixed!!!
