This is gambling in casinos not sports betting. Here it is luck which is all that matters. Getting a 100% win rate is very possible for a very lucky person, but the question is "for how long?" once the player runs out of luck they will lose again. So it is technically not possible to get a 100% win rate since the house edge will make you go bust at some point of time.
100% win rate never happens not even in sports betting. you will end up losing sometime and even if you have a 100% win rate it means you have only been playing for a very short time and you have only a couple of bets.
but yeah there is a better chance of winning in sports betting that there is in playing dice because of the skills you use there.
