In addition to the opinion of forecasters, you should have your own opinion, which you should count on most of all, because you will be risking your money, and not the person who gives the forecast. I understand that some people want to trust the opinion of forecasters, because they think that they are more experienced in this. But in fact, they can do this just for the sake of views, for their own purposes. I do not see much point in trusting someone's opinion, rely only on yourself, otherwise it will be very difficult to learn anything.
Good point, there are people who thinks that those forecasters are better than them but in reality they can also do the same if they just focus and learn the fundamentals, as there are factors that really affects the outcome of the game, though still luck is another thing to consider, forecasters are just claiming something but the accuracy can't be 100% maybe some of their predictions may fall to win but it's not always that same outcome will take place.
I am sure that those who really put high trust in someone who is called a prediction expert are some of those who are really unfamiliar with what and how the concept of gambling actually works. This belief is like a kind of tradition that is naturally formed in the minds of ordinary people, but actually when we go back to understanding what and how the concept of winning and losing in gambling rationally works, then you will not really put too much trust in those who are called experts.
Because there will definitely be a lot of doubt in your mind when talking about experts in an activity that cannot be fully predicted accurately, and I am sure as you said above that whoever they are, even though they are called experts, it still does not guarantee that they will always be able to predict the game 100% accurately, meaning that there will always be certain times for them to experience defeat. In the end, this is actually a choice, it doesn't matter if you want to make their predictions a choice as long as you gamble without exceeding your limits in the sense of only betting the amount that you can afford, it's like the idea of relying on luck and other people's skills to produce something.
