You are incorrect the tickets are not "sequentially in the order' You could be the first player or the last player and get ticket number 1-1000 there is 100% no way for someone to pick there numbers its all 100% random.

Any visitor to your site can clearly see that tickets are not randomly assigned, as I've already shown in this screencapture. The ranges in blue beside the players' names represent the tickets that a player holds. The n-th player to join will always hold tickets (n-1) * 10000/m +1 through n * 10000/m, where m is the total number of players. There is nothing random about it.

In addition, as I have also already explained, random ticket assignment would make it even easier and not harder to cheat with your current "provably fair" system:

If the ticket numbers were assigned to players randomly it would be easier—even trivial—for the house to cheat, not harder, because the house could simply "randomly" assign the winning ticket to a player it controls. There would be no way for players to verify that the tickets were indeed randomly allocated in your current system.

Just to humour you I'll revise my explanation for that scenario:

The house generates the lucky number 6000 and an arbitrary number of legitimate players join the round. The house joins the round itself with a player they control and "randomly" assigns the winning ticket to that player, ensuring the win for the house.
