Poker and gambling have now become legitimate professions and many feel that poker is a sport because it is skilled based. Because gambling and poker have been elevated to the level of a profession, students of gambling and poker from around the world are seeking out mentors, study guides and perfecting their abilities. While many professional poker players are self-employed, others of higher caliber take the profession to an entirely different level. Those poker professionals obtain corporate sponsorship and thus create other streams of revenue. Poker and gambling professionals that receive corporate sponsorship then become companies of their own and that is where the real money starts to roll in.
