In card games of course it involves experience, yes it involves luck but there are people that through experience they developed thier analysation skills, intuition and guts. A experienced gambler knows and feel when to stop and when to have a bet.
Gambling is hard tho' thats why it is a gamble you either win or loss. But experience is important because a long the way you will learn how to bear defeat and know when to stop.
Mostly I agree with you, but certainly not about sports betting. Just like playing poker, we need an experience that we get with time - the longer someone plays, the better should be. With sports betting is needed not only experience but also high knowledge about players and league situation, even politic decions inside clubs. For me sports betting need the highest skills to be profitable.
In my own opinion i think experienced is great advantage for us to win on gambling since it can help us to familiarize the flaws,stats,on what to avoid,which team is strong and everything. And that could make us earn more advantage rather than betting on unfamiliar thing on unfamiliar times. Remember newbies or unexperienced people are most likely the losers on gambling since they doesn't know on how to act right when betting time is on.
Experience does not benefit sportsbetting but rather all gambling games. Like for example, an experience player will know how to adjust his bet whenever he is trapped in a tight situation. He also know when to have a timely exit when he is winning to book a profit. He can also use his experience to minimize his loses. All in all, experience does not help us in winning but in making us realized to stop when situation is not in favor of us.
