I want to go forward in time, get a sports book with the results of all the Kentucky Derbies between 2018 and 2040, then I want to come back.
I want to go back in time and warn my friend Jim that a drunk driver is going hit and kill him so he can avoid it.
That's "time travel".

The consequences of time travel are fun to think about. You provided an altruistic reason for going back in time, but failed to mention the downside. Maybe if Jim doesn't die, he ends up killing a young mom by accident who would eventually produce another Einstein if she had lived. By the same token, if you go into the future for the sports book, how do you know your presence in the future doesn't alter the timeline, thus making the sports book meaningless.
We'll never know the answer.
