I fell for the UCL qualifiers trap, betting on favorites and many of them lost,,, Bodo/Glimt for example. I feel like after their performance against Roma now they are weirdly having low odds.

juts don't bet on events with teams you're not familiar with, skip CL qualifiers and definitely, definitely skip Conference League qualifiers. Premier League and Bundesliga kick off in three weeks, just

This is 100% true. If you are not watching the games of the teams you are betting on, there is a 90% chance you will lose. If you are wagering on the teams at the top, teams that we all know, and you have watched them like at least half a dozen times last season, and probably all friendlies even this year, then you would know how to bet on those teams and what could happen.
Don't get me wrong, we still get it wrong even when it's the teams we like to watch but that is at least a bit less riskier because we know them and it could just be a shock to us. But, when you wager on a team you have never seen before, or at least watched like maybe just one game in a whole year, then its risk not worth taking.
