Gambling is all on luck; no matter how experienced a player is, if they do not have luck in their game, they cannot win. Because, even when some individuals go and have a better chance of winning for teams they know are really powerful by betting large sums of money, it is still all about luck.  In football, it is not always about powerful teams; some weak teams might surprise a good team by defeating them, and that’s up to today. I do not believe that gambling is solely based on knowledge or experience with sports.
