Recently a rush of sports betting sites has been promoting themselves as way to make massive amounts of money. There are two major reasons why sports betting is a poor choice to earn money compared to online poker.

In sports betting, there is a large element of gamble involved, since for the most part you must count on too many variables which are against you in the bet. For example the line (or, point difference) is set through the house. This line usually is set to ensure that it equals the game to a more fair and balanced number, therefore making it close to even odds in determining a winner.

This fact alone makes sports betting more of a gamble, since it's harder to depend on the merits of each team. Additionally, additional circumstances, for example the team's mindset, the weather, good casino or any injuries to a player throughout the game, force sports betting to be a gamble or game of chance.
