Experience is important everywhere, but here in gambling games, the most important is to have luck. You can have all the world experience, but if you don't have luck to roll the dice and win the prize, you won't go ahead.
Experience can be more useful if you are a sport gambler, any other game you need mainly luck.
For gambling too, experience is more important but probably in lesser percentage than luck factor. Again, not just in sports betting, everywhere you can make use of our experience in gambling world. Still I am again saying your experience will be influencing in the lower percentage compared to other factors.
In this world you can buy anything for your money but you cannot buy your experience. When no other gamblers will be having experience, and if you are having it then you will be finding more chances to have extra edge compared to other gamblers.
Gambling results are purely dependent on how lucky you are on that particular day. Still your experience may help you to get comparatively better results.
