Analyzing numbers is fun, but there is hardly any reason to believe that lotteries, at least government-run ones in democratic countries, should be anything other than random.
If you want to find an edge in lotteries, look for flaws in the prize structures, not the number draws. There's the famous story of the Midwest couple Jerry and Marge Selbee who did just that. They found a lottery with a prize structure such that jackpots that were not won were distributed down to lower prize categories, dramatically increasing the expected value of the return. They bet big, and it paid off. At a later point, MIT students independently found the same flaw in this lottery. Eventually, of course, the state administrators caught on to this flaw and changed the rules. There was even a movie made about the story: "Jerry and Marge Go Large". (I think the lottery game was called "Winfall" if I recall correctly.)
I think you would be hard-pressed to find such exploitable flaws anymore, but there are one heck of a lot of lottery games out there, so it's entirely possible a few of them could have some actionable prize structure flaws.
