Oh and for your example, I know how that it reported
“For example, if you place 100-$10 bets on Sunday football, and most of your bets lose but one comes in big at 100:1, is that reported as $1000 win and $990 of losses, or is that reported as a $10 loss?”
this would show up on a summarized statement as $1,000 in wagers, $1000 in winnings. Net statement: $0. There’s really no loss column to be had. Wager is your cost basis, regardless of outcome. Winning is your result, regardless of cost basis. Bet $10 on a slot machine spin and it only returns $5 ($5 losing spin) that would show up as Wager $10, Win $5.
you could get a bet by net print out that shows each individual outcome,and for a small time player that might be possible. But any extended play, especially when slots or fast pace table game is involved would have a really large list of individual results, most of which are only available 10 results per page at a time on a website, and not in some downloadable form
