ELI5: If the odds of winning a $600 million mega jackpot are say 200 million to 1, why wouldn't a billionaire buy 200 million tickets, win the jackpot and profit $400 million?

EDIT: I know about taxes, I know it's not practical, I know the odds, I know billionaires can spend their money better elsewhere, I know others can win, I just wanted to hear a clear cut answer!

200 million to one is the odds of getting the right ticket. However the right ticket can be purchased several times. As such you could wind up spending 200 million and only getting 50 million (taxes suck). Further, they take more taxes if you choose the lump sum payment vs. the 20 year payouts.

To put it in perspective, the recent 658 million jackpot was won by two people both of whom took the lump sum payout. After taxes they each get 158 million. Still a lot of money, but not if you paid 200 million for the ticket.

There are better things to invest your money in if you are a billionaire.
