out of 10 wins I think there will be some losses and its not sure if the wins are worth the losses because even though betting strictly on every sport does not guarantee always wins.
I know what you mean if a gambler gets a big win from gambling or gets a win every day after that the winnings are invested elsewhere which has a little risk that does not mean he not believe in his skills but he only thinks in the long term and someone does this have a good mindset to manage their finances. so gamblers like this can be said to be professional gamblers.
That's what you are going to end up with depending on the results and should be considered a bit different. I think it's quite important to calculate the wins accordingly. For example, if a team loses once every 10 games, that means if their odds are 1.40, that makes 9 games to end up with 1 loss equals to end up making a profit.
That is not really an issue and we should bet that, but if teams lose like 3-4 times out of 10, then it would not be a thing that makes on the long run. This is why I think we should consider the situation to be profitable depending on the situation, check what the team is doing and check the odds and based on something like that will end up with a greater return on the long run as well.
