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

In sports betting, there is a large element of gamble involved, since for the most part you need to rely upon too many variables that are against you within the bet. For example the line (or, point difference) is set by the house. This line usually is set to ensure that it equals the game to a far 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. In addition, other factors, such as the team's mindset, the weather, or any injuries to a player throughout the game, force sports betting to be a gamble or game of chance.
