Sportsbooks in general don't mind winning players though, especially big ones. They make money off the vig and move odds to get equal money on each side of the bet so that they'll make money either way.
As someone who has worked in the sports betting industry, it depends a lot on the bookmaker. UK retail bookies hate anyone with any savvy, and will ban their accounts fast. Ditto "weird" betting that looks like it might be machine-run. Their business is taking old folks pensions from them.
OTOH, exchanges love all kinds of gamblers and won't ban you for winning any amount. "Smart money" Asian bookies will bet against anyone because their job is to have a better model than you. (Of course, there is a max bet on any offer, and the odds will move if you hit them hard enough.)
Also, everything in the abstract of this article is either old old news (strategy-wise) or plain wrong in light of the actual business of sports betting. "Implied odds" has been around forever, and real companies make real, consistent returns from arbitrage and "statistical arbitrage" on implied PDFs and have for years.
They hate “sharps”, winners who win through skill exploiting lines, they love those who win by chance. Sharps will continue to bleed them, the lucky fish often become whales whose luck fades over time.
You are confusing luck with expectation. Luck is the deviation from expectation. I've seen terrible poker players win a big tournament, or crush cash games for months on end, and quit their jobs because they mistakenly believe they are skilled at poker. Their positive deviation above their actual expectation (their "luck") soon evaporates, and they moan constantly because their results begin to actually match their expectation, or even worse, they get "unlucky" and their losses are greater even worse than their expectation.
The books rarely balance up though, especially for markets with more than two outcomes. Football/soccer has win/lose/draw (and you can never get enough money on the draw, as hardly any amateur is going be watching a match cheering on a draw!)
Horse racing is even worse for the bookies, with multiple runners, their books will rarely balance, and the standard outcome is a loss if the favourite wins. Any outsider winning a race is a ‘turn up for the books’. (n.b. this is for UK style horse racing betting, where the bookies offer fixed odds. Pari-mutuel or pool betting doesn’t have the same problem)
