Patterns of random numbers are just that -- they are random. If a pick 3 game drew one straight combination exactly once every 1000 drawings, then you could draw a conclusion that the three digits are not being drawn independently. Such is not the case. Sure, random numbers seem to follow "patterns"... which of these three, a pair, etc... but all those patterns are random and they are all unpredictable... because they're random!
But if you are picking numbers and winning consistently, congratulations. You're either very lucky or have some magical ability to predict the future. If the latter, why don't you do this for Powerball? You could win millions of dollars instead of just a thousand.
There are approximately 80 drawings of pick 3 every single day in state lotteries across the country. That's over 500 a week. It isn't difficult to guess numbers and be right with games drawn that frequently and probability of success in any single game being relatively high (1 in 1000 for a straight, 1 in 166 or 333 boxed, and 1 in 100 for front pair or back pair). When you make predictions for pick 3 games in many states, you are bound to be "right" just because of the volume of predicted numbers and frequency of game drawings. That is not evidence of any state lottery rigging their games. That's just picking numbers that will randomly match other randomly drawn numbers.
In order to have statistical evidence of a rigged game using sets of past drawings, you need a large amount of data from one game. Pointing to numbers in various states here and there is statistical noise. It has no meaning. But if you believe that you are right, carry on. Keep winning or keep complaining that the lottery switches gears and changes to a new "pattern" just to throw you off.
