it's not risk-neutral
you're misunderstanding risk and probability and the complexities involved in mutliple prizes, and the way the lottery works.

You could possibly describe it as risk neutral if you played over significantly more than 14,000,000 draws, if all the money paid in went into the prize fund. But it doesn't and anyway you don't have 269,000 years to play.

It's not stupid to play. But it's stupid to try and base your chances of winning on any probability calculation related to the chances of any series of numbers coming up. You might win. it's not likely, but you might.
