No guarantee at all, even the underdog can snatch a win against the heavy favorite, and it's not unusual as we've seen a lot in terms of sports betting outcomes, not just in football, but also from different available games that we bet on, and likewise, you need to assess, and you need to compare performances between two competing squads to analyze the winning chances, and since that it's not just win or lose options you can also predict scores and players and teams stats, there are many additional alternatives aside from who's going to win the game, just need to adjust with your knowledge and continue learning how you can predict the next possible outcome.
But then again, you need to base your pattern and strategy according to your experience and according to how you understand the game, there's an edge that you can develop when you know the squad or teams that you are following and supporting for your picks.
You can only see favorites and underdogs from the odds provided by bookies, but you don't focus on that alone, you need to evaluate where you can see the value because sometimes it could be overvalued/undervalued, so if you are good in analyzing, you'll see which team will give you an edge and eventually that will help you increase your winning percentage. Additionally, you need to understand how to manage your bankroll as well as winning alone is not enough, even if you have a high percentage of winning but you are not good in managing your bankroll (like chasing losses), you'll end up losing.
You know, you can't be frustrated when betting as you are up against an algo and bookies has bigger bankroll, could limit your bet if you are winning, so the best way to be in the profit column is to be discipline, and take it slow but on a consistent manner.
Yeah, but then, constantly winning can be dangerous for a player, even though constant wins isn't an easy fit, it takes much more than extra hard work to arrive at such a level.
Constant winning, most especially in sports betting us very possible, but just like you pointed out, the bookie can limit an account that is constantly in wins, this I believe is the reason why someone told me one time that, if as a gambler, you are very good in a particular sports and you are contantly winning, you love the casino and want to continue to bet on your favorite sports on that casino without ever getting limited, then you have to find a way to balance your winning and your losing ratio, this actually does not mean one should on purpose lose money so their loses be equal to their wins, but it simply means that, one should not just focus on that particular game they are very good on, to be on the safe side and avoid being limited, one should diversify the games they play, like from time to time., play other sports games that you are know you re not really good in, even if it's with a very small amount of money, this way, the algo or the bookie will not flag your account as milking their system, which usually results to account limitations.
