~ Luck is another factor. ~
In my opinion, luck is a significant factor in sports betting. Yes, you can analyze the recent performance of the teams, find out about currently injured players, formations and stuff, but all of those things can be done by other bettors too, right? Hence we are getting the odds we can place our bets with. For a team that is very likely to win the odds are usually around 1.10. You have to risk $100 to possibly win just $10. And because of bad luck there can a draw, which is pretty often happens in such cases, and then you lose your $100. So, I'm not sure of to what extent luck affects sports betting, but I feel like it's a big factor.
Yesterday we just witnessed it except that it went to far and not stopped at a draw,the odds of Argentina at 1.11 suggested to me and I nearly did it that to place 1000 dollars to get 1111 ones as a sure thing and luckily I didn't bet because we all know how it ended.This means that luck truly plays a very important role even in sport betting although luck is relative here,sometimes like that game yesterday it can make you lose your bet but this happens rarely different from the slot machines which happens all the time,most games you can predict with skill in sport betting.
