There a lot of combinations with in a lottery and yes, you don't win unless you don't try doing so. Lottery is just base on pure luck and it is always either you win or you lose. Though its always a higher chance of you losing but the thing is the family that won that lottery is very lucky to have that money. Well, Congrats to those that won that million euros.
This does not really work all the time and therefor I suggest you to stay away from lottery and the combination stuff and rather look at the crypto speculation and trading thing. The chances of making things happen in lottery even by applying this concept of combination might not always work for you need huge numbers of tickets/entries and that is not possible.
Agree, it's not worthy at all and doesn't stick on that idea. I know a lot of people who still bet in the lottery until they got aged, didn't still win. You don't need a lot of effort in the lottery, means it's also not an easy win, it will take you a million of days just to win there.
