Maybe if you've been following the lottery from a certain casino and have made or found a pattern, you can know what will come out. But it takes time to analyze the pattern until you find a pattern that will come out after the current pattern. And maybe some people who can or know about drawing up patterns can win the lottery but for most people, I think it will be very difficult.
In the past, one of my grandfather's younger siblings used to analyze the lottery numbers that had come out of the casino and try to figure out the pattern. But he still couldn't find it; strangely enough, when he just made a random guess about the numbers that would come out, the numbers actually came out. But unfortunately, he didn't buy the numbers and instead gave them to someone else and that other person won. But he got the money as thanks for giving the numbers.
The truth is that even if you take the time to make an analysis like that there is no way to be sure you will find something, this is similar to what some gamblers do when trying to analyze the roulette.
They keep track of the numbers and they try to find out if there is any bias on the roulette, however if the roulette is in good shape even if you take the time to crunch the numbers you could find nothing except that the roulette is working as intended, making all your effort a waste of time.
