Any results that depart from average should be expected to be temporary.
I don't pay too much attention to what people have to say about their results using their chosen "system", but I have noticed a few things. I'm pretty sure that nobody has claimed to have a positive cash flow as a result of playing the lottery. People may have a period in which they do very well, but it's preceded and followed by periods where they don't do so well. As I've already said, we should expect some people to do better than average purely as a result of random chance.
Plenty of people talk about patterns, but there appears to be near-universal acceptance that these patterns come and go. Hindsight is always 20/20, and finding a pattern that has happened in the past as a result of random chance doesn't help predict what will happen in the future. You can easily see this by flipping a coin a sufficiently large number of times. You'll find several "patterns" where 5 consecutive heads are followed by a tails, but if you check every occurrence of 5 consecutive heads you'll find that the number of them followed by a tails is about the same as the number followed by a 6th heads.
A graph of a normal distribution over a given period of time will look about the same regardless of when that period is, but the details will change. Make a list of the numbers drawn over a few different periods spanning 100 drawings and then draw graphs showing how many numbers were drawn once, twice, three times, etc. The graphs will be similar, but the indvidual numbers won't stay be in the same place. For one period 17 might have been drawn the most number of times, but in a different period it will have been drawn about an average number of times.
