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?
I consider fantasy sports betting is selective scamming technique and they brand it as skill game not as gambling which itself is a wrong statement its more risky and perfect definition of gamble than choosing which team will win either this or that in sport betting. Also the rewards are not transparent so it's a big question mark whether you can trust it for big amount.
