Maybe there is not much point for us in listening someone's opinion but that will not be like that for other people because many people wants the easiest thing without having difficulty to analyze the bet. When they get more information about the prediction and see many people have the same pick, they will just follow without think too long. They think that public opinion will have more chances to win especially if they can see some influencers also say the same thing so that will be easily for us to just follow and doing the same thing like them.
If you believe the statistics, most players lose more than they win, so you could assume that public opinion in choosing a bet is a bad choice, because this bet will fall into bad statistics. In fact, I do not worry much about how much my bet can coincide with the bets of other players, because I do not try to understand how much this coincidence is, I just bet on what I think is a good choice. )
I agree with you that most gamblers lose and still find more interest in continuing to gamble. Gambling is an addiction for many people which they can't quit even if they want to but at present their willpower is enough to get rid of the addict because he needs a lot of money to continue gambling regularly. There are also some gamblers who take part in gambling for fun and continue to gamble even if they lose. For them the tendency to lose means that they tend to continue playing more because they consider gambling as entertainment rather than a source of income.
