Buy all Lotto Combinations - Win Big

[South Park]

what does the "least likely combination" meant? do they mean the least likely to win or least likely to be picked by other lotto buyers?

although the story sounds good it is incredibly risky(at least for me) even if they got about 82% of the combination. I wonder if they did this again or if the lotto company(not sure what they are called) placed a rule or preventive measures to prevent this kind of thing happening again.

Most likely what this means is that the gamblers kept track of every single result of that lottery and then they tried to see if there was any bias in the results, if there were some numbers that appeared not as frequently as they should then they avoided those numbers and instead concentrated themselves on the numbers that appeared more frequently, while from a purely mathematical point of view there should not be any bias if the method used to try to pick the numbers of the lottery is flawed biases could appear and as such the methodology used by these gamblers is correct.

A friend of mine thought of a similar idea once, but hypothetically because he wouldn't want to get in trouble. The idea was to create a community via an app, and this community would target some specific lottery and buy out as many tickets as possible (but not all of them because it's not realistic), and they all don't spend much on the venue individually, but in case the community got the ticket right, the reward is split equally between all participants. So it's not like there's a guarantee of winning, but there's a way higher chance of getting some reward than when one simply buys a lottery ticket.
But nowadays I think such an enterprise would be targeted and outlawed.

your friend must be rich because the possible combination are millions and that will cause him millions for buying all tickets but asking for help is a smart move to do to not all shoulder the payments like what the character did in the story but my question is who held the funds in the group that he created, was it your friend ?
 i will not easily trust my funds to random guys if there is no escrow involved but i will maybe if i know the members of this group .
