>>>No state lotteries in 1960! :)<<<
the first state lottery, the New Hampshire Sweepstakes, didn't start until 1964 and was the only state lottery for a long time. But there was the Irish Sweepstakes which started in 1930 and was a big deal in the USA (although technically illegal). Lucy Ricardo even bet on it. Bilko may have had an episode where they were listening to the radio to get Irish Sweepstakes racing results. The ultimate result was based on a horse race with the horses each representing a randomly selected number on your ticket.
I'm not a Stephen King fan. He said this book would hopefully get people to read him who normally would not. I certainly was one of those. Except for Shawsank (which I don't particularly like because of the prison corruption angle and that one of the star convicts was a black guy in a state that had about two black guys in it at the time) and Carrie (which I thought was kind of stupid).
I also don't really like Franco since Freaks and Geeks days. I thought this was ok. a lot of shows today have overly complicated extended plots that are hard to follow. There is some of this here but much less than in the book. (Complicated plots are better in books because you read at your own pace and can flip back to previous pages). The flaws in the plot elaborated here by others I think were accounted for as the rules of time travel in the book. They will probably eventually be elaborated on in the mini series. I do think the first episode was long. And it looks like the Kentucky plotline is going to be made bigger than in the book, consuming at least one or more whole episodes at least. And it looks like he gets a sidekick there.
