However, you can become a profitable player with enough hard work and experience. In fact, some professionals still earn six- or seven-figure annual revenues from the game. The simple answer is yes, you can make a living by playing. Profit margins for winning sports bettors are often slim, and large amounts of money must be wagered to make enough profits to earn a living.
Bet lines are set by bookmakers and sometimes change depending on the amount of money wagered in the game. Regardless of which game you choose to play, the odds that the casino will win your money are greater than the odds that you will win the casino's money. Bookmakers make money thanks to big guys, casinos are guaranteed to make a profit due to the house edge, and poker rooms receive rake from every pot. Stop gambling your money, find an advantage, try your paper-based system, and when you feel ready, don't risk more than 1% of your funds.
This means that your funds must be large enough for the stakes to be big enough to make as much money with the advantage you create. You need to have enough money in reserve to live on while you build your funds enough to withstand the ups and downs and eventually start taking advantage of it. The casino does not intend to bankrupt a player in one go, it just wants to make sure that, in the long run, players come out with a little less money than they had, leaving money in the casino's pocket. It's worth noting that any money earned while playing is classified as taxable income by the IRS, and you can calculate your taxes with the lottery tax calculator.
And when you have a month where you lose money or don't earn enough to cover your bills, you still have to pay the bills. So, if I offer you 1.90 (decimal odds) for each coin flip, your money will end up in my pockets after 200-300 coin flips. The constant stress of playing with an advantage and the need to win a certain amount of money each week can make you take a toll.
