Both are skill based yet former is considered sheer gambling while later is not. Fantasy sports has become norm, while on the other hand if people come to know that you bet on sports you'll be met with eyebrow raise.
^ that's my opinion. What's yours? Do you consider both of them same or different?
Way different. That's like saying poker and slots are the same. One you are playing against the house with Odds skewd in their favor, the other you are playing against other people. If you are better at something than other people over time you will win more than they will. It's the whole against the house or against other people that separate the 2.
