The odds are +2433 for that 3 game parlay, if he bet 2 dollars he would have got a payout amount of $50.65 for a profit of $48.65.
Odds: 1.91 (-110) x 1.95 (-105) x 6.80 (+580) = 25.33 (+2433 Vegas Format)
A two dollar wager would thus make a profit of 48 dollars and 65 cents.
So if "the dude" says he won $4,400 dollars that is possible, all depends how much "the dude" wagered. He could have also won 5 million dollars or 500 dollars, who knows? That screen shot doesn't show the wager amount so we will never know how much "the dude" won.
