If you look at the multi-portal online gambling sites you will find three main verticals. These are poker, casino and sports betting. In all three streams players need to take risks and put up a stake in order to be in with a chance to win something more. But the three online gambling verticals are fundamentally different.

In online poker you are directly competing against other players. The online portals that host poker games make their money through a rake. This is a small percentage of the pot that goes to the winner. There is some luck involved in online poker, but it will even out over time. So whether you make or lose money will depend on your skill level as compared to that of your opponents. If you consistently play against weaker players then you will win most of the time. The point is that players less skilful than you will not want to play against you and you will not play against better players. Players that have achieved the highest level of skill can, and do, depend on poker for a living.

In online casino games all players wager against the house. There is no interaction between players. This is true of all online casino games, whether roulette, blackjack, slots or any other. You make a bet for which the payout is specified in advance, should you win. These payouts are always less than the mathematically fair payouts. So at the end of the day the online casino will always make money in the aggregate. Some lucky players will win and some unlucky players will lose. Most players will not be consistently lucky in the long run. It is foolish to depend on online casino gambling for a living.

In online sports betting you wager on the outcome in which others are engaged and you can in no way have any influence. The odds offered are higher when the chance of winning is lower. So, bigger expected payouts are linked to betting against the expectations. The odds are determined in a way that creates a house edge for the operator. Your knowledge of the game and the contestants is critical in this online gambling activity. But this cannot guarantee that you will win. More renowned teams sometimes lose for no reason except that the other team was better on the given day. Again, it is not wise to depend on online sports betting for a living.
