You can simply make a bet on "under x goals" on those games. I wouldn't say that the chances of losing are lower or higher than making a bet on "over x goals". We had many games where the majority of people thought there would be a lot of goals, but that didn't happen... and many times the opposite thing happened, we didn't expect a lot of goals (defensive teams, injured players, bad weather, etc) but exactly that happened and both teams scored a few.
Yeah, I was going to say the same thing. We can do this instead of avoiding them. That should save us from hassle. Maybe he only had a bad experience on this type of matches, and that is why he can say that the chance for us to lose here is higher. There might still be bettors who are good at it and prefer it over the other. These bettors can also say that their winning chance on them is high than compared to other modes of placing a bet.

This reminds me of the song which has a lyrics ' opposite do attracts ' . I think that was also its title. It's interesting on how true is it. I never thought of this before, hehe. For sure, many of us didn't expect that too, this is why I got tired of expecting on something, especially if I think that there are no assurance on it.
As you wrote "My results vary when I don't do enough research", when we rush with choosing the games we plan to bet on the chances for us to make a wrong pick are higher. We need to spend some time searching for the right games, and the time spent on that is not wasted. But sometimes it's easier to say than to do it, at least in my case. But I am sure that people who decide to improve their winning rate will think about spending more time searching for the right games and deeper researching of those games before final selection.
By the time he wrote that, he must have realized that he already answered his own question. Apart from spending a time looking for games, another thing that we spend our time with, is when we analyse the game that we choose. They say that if we enjoy the time that we spend, it is not wasted but I know there are people who find analysing boring. Hence, they just skip this part and bet instantly.
