Actually some players just gamble in fear and they won't take their own personal decision. They fear failure despite how much they have, they would go with the public in a decisive match like El Clasicos and this is talking about the newbies. So control or the amount of money that you have many times may not matter especially if you have been on a losing streak. Loses can actually destabilize a gambler, get them confused and so they wager from public opinion. Failure has no followership and that is why when you are winning you are likely to keep doing that which is producing results while a loser stumbles with different ideas.
People with such habits and mindsets should stay away from gambling because they will most likely only lose money in the long run. If you are not confident enough to make your bets yourself then you are not going to have stable winnings for sure. You can't rely on public opinion all the time, you need to have your own thinking and understanding and you should be able to do analysis yourself if you want to become a profitable sports bettor.
Someone cannot expect to stay profitable in the long run if they aren't knowledgeable enough to make their bets based on analysis and research they have done on their own. Researching about public opinion and views about a certain event can be a part of your analysis but it shouldn't be the sole reason behind your decision.
