My opinion is that we tend to overestimate the weight of knowledge in sports betting. In the end, our knowledge on sports is based on news that is available to everybody, so it has to be hard to be competitive when this info is public, left aside that luck plays a major role too in big wins, while "sure" bets (if there is anything like that) have low odds in exchange.
I frankly do not see the possibility in the metrics with which their analysis or conclusion is drawn. Even the best of analysts, when it comes to gambling, can have his professionalism challenged with the outcome of a speculation.
The gambling companies are in it for business and if everything goes as a professional analyst speculates then, it's only a matter of time before there is no business for the company.
When it comes to gambling, picking the right number that gives the winning or becoming the lucky number is quite and most important at some point, and at best one needs to look out for that specific aspect of risk management and possible outcome of things in the long run.
This is a clear explainer to the fact that, lottery is purely based on luck, winning the game has nothing to do with one's experience, or how long the person have been playing, or how much one have invested in the game for the long term, the only way to increase ones chances of winning is to buy and hold as many tickets as number, and if the lottery is one that involved numbers, then tickets should be different numbers cause that the only way to increase one's chances of winning the game.
You are correct in that matter; it is true because only 4 or 6 digit numbers are chosen, and then you just wait for your luck if your numbers are all drawn in the raffle draw itself.
That's why the others don't; they take care of the numbers they always use in the lottery, believing it's their luck, and often the birthday combinations they use are those that are precious in their lives, either the date of their spouse, the birthday dates of their children, or their birthdays. That's what others do.
