@Betwrong: all you need is a ticket and a good portion of luck to win, so
1 ticket is better than none at all. Good luck.

That's right, but I checked past winners since the round 63, and I can see that normally it's players with more than 10% of tickets, who win the prizes, and the latest round is not an exception:

It's the same as with mining. Yes, it's completely random, and someone can mine a block while solo mining with just one miner, but in most cases pools with a lot of miners successfully mine blocks.
Yet, there are cases like this one below

when someone with just 0.169% of all tickets won almost 4 ETH. So I bought one ticket for the next round. Who knows, maybe lady luck will smile at me this time. )
