Context paragraphs:
Parimutuel betting: Parimutuel betting (from the French: "Pari Mutuel" or mutual betting) is a betting system in which all bets of a particular type are placed together in a pool; taxes and the "house-take" or "vigorish" are removed, and payoff odds are calculated by sharing the pool among all winning bets.  In some countries it is known as the Tote after the totalisator, which calculates and displays bets already made.

Betting pool: A betting pool, sports lottery, sweep, or office pool if done at work, is a form of gambling, specifically a variant of parimutuel betting influenced by lotteries, where gamblers pay a fixed price into a "pool" (from which taxes and a house "take" or "vig" are removed), and then make a selection on an outcome, usually related to sport.  In an informal game, the vig is usually quite small or non-existent.  The pool is evenly divided between those that have made the correct selection.  There are no odds involved; each winner's payoff depends simply on the number of gamblers and the number of winners.  (True parimutuel betting, which was historically referred to as pool betting, involves both odds calculations and variable wager amounts.)

GBEA was acquired by Ladbrokes PLC in February 2013.  BETDAQ is the second largest betting exchange operator with approximately 7% market share.  BETDAQ allows people with different opinions on the likely outcome of an event to bet against each other.  A betting exchange allows people to bet against each other rather than against a bookmaker.

Tote betting: The Tote is the only bookmaker in Britain which is allowed to offer parimutuel betting on horse racing.  Other bookmakers offer a Tote service through syndication, while other bookmakers will accept a Tote bet and pay out on exactly the same terms as the Tote.

Lottery betting: Lottery betting is the activity of predicting the results of a lottery draw and placing a wager on the outcome.  Lottery betting (also known as lotto betting) is a form of online gambling, run by licensed betting firms, where players place bets on the outcome of lottery draws instead of buying physical or online  tickets via official lottery operators.

Vigorish: Vigorish, or simply the vig, also known as juice, under-juice, the cut or the take, is the amount charged by a bookmaker, or "bookie", for taking a bet from a gambler.  In the United States, it also means the interest on a shark's loan.  The term originates from the Russian word for "winnings", выигрыш "vyigrysh".

Numbers game: The numbers game, also known as the numbers racket, the policy racket, the Italian lottery, the policy game, or the daily number is a form of illegal gambling or illegal lottery played mostly in poor and working class neighborhoods in the United States, wherein a bettor attempts to pick three digits to match those that will be randomly drawn the following day.  In recent years, the "number" would be the last three digits of "the handle", the amount race track bettors placed on race day at a major racetrack, published in racing journals and major newspapers in New York.  A gambler places a bet with a bookie at a tavern, bar, barber shop, social club, or any other semi-private place that acts as an illegal betting parlor.

Betting exchange: A betting exchange is a marketplace for customers to bet on the outcome of discrete events.  Betting exchanges offer the same opportunities to bet as a bookmaker with a few differences.  You can buy (also known as "back") and sell (also known as "lay") the outcome, you can trade in real-time throughout the event and you trade out to cut your losses or lock in profit.  Bookmaker operators generate revenue by offering less efficient odds.  Betting exchanges normally generate revenue by charging a small commission on winning bets.
