No, you're fooling yourself if you think there is no predictability to the numbers or that some numbers don't have a better record nationwide of hitting then others.
Professional lottery people who do weekly predictions know that if you take the 24 hottest numbers for the week nationwide for next week's prediction, you will average about 30 hits per day nationwide over the next week. You can't make money playing this way because of the low payouts, but if the game were played at casino payouts of say 95% like roulette people would be singing a different tune about predictability.
As for Pick-5 and Pick-6 there are real ways to reduce your odds in some drawings such as not playing any of the numbers from the previous draw which sweeps half the possible combinations off the table on the days this strategy proves correct which is almost half of the time, less in smaller games more in larger.
Playing all the numbers means never not having ALL the winning numbers among your lines which makes one hell of a difference in your potential to win a jackpot as you can't win one when missing some of the numbers.
All you have to do is study the history and you can see what winning tickets are like. It isn't all that hard to make ones that look like those, where you have a real chance to win unlike quickpicks where no matter how many you buy there is no guarantee of a win or having all the winning numbers among those you are playing.
You can play smarter then the other people in line. BobP
