I do play the four major sports on draftkings but my time spent on there has decreased dramatically because my team usually finishes in the lower middle of the pack and hence, no wins! The people who do win, from what I've read POUR over stats and know practically every detail about how a pitcher does against a certain team, what player has the highest batting average against a certain pitcher and how a player they are interested in picking has performed over the say the last ten games. In my opinion, a lot of it is luck though too! Sometimes a pitcher I've picked just doesn't have the stuff and gets yanked after the third inning. I also have chosen hitters who were hot but oddly cool off now that they're on my roster, go figure. Good luck!
