Most probable reason is they beleive that they know that game much better and also about the team they are going against so it's most likely they will bet on the sports they are watching most often. Anyway 50/50 chances games look like easy chance but its not cause one small move from the least favourite can make them to move in a comfortable position. But the reason is simple we believe we know the game deeper than most people out there.
We believe that once we identify the sports that are no longer a 50/50 chance, we can gain an advantage, and focusing on just a few sports in sports betting increases our chances of success. The reality is, the majority of sports bettors are losing money, which is enough for sportsbooks to stay in operation for a long period. If we are one of the few who can make a living in sports, then we can live a wonderful life as a successful professional sports bettor.
Those who are serious in sports betting are dreaming of making a living in sports betting, that's my ultimate goal as well.
Sure, sports betting enthusiasts think they're experts, placing wagers like champs. But, folks, even the smartest fan can get slammed by a shocking outcome. That's why it's called "sports betting" – not "sports certainties"!
Confidence in our wisdom and skills? Great. But let's not ignore sports' wild side. A tiny twist or surprise injury can flip the game, no matter how well we know the players.
Dreaming big, aiming for sports betting stardom? Go for it. But stay grounded, accept the risks and curveballs. Remember, "don't count chickens before they hatch" – or winnings before the final whistle
That should be everyone's attitude so they won't be disappointed if they lose the bet.
Let us say, you are living and breathing that sports, and you still lose. Remember, there are some angles that you can't be in control of.
Just like you said, unknown injuries, last minute change of lineup of athletes, or new coach, or maybe weather can influence the outcome.
But of course, if you are familiar with the sports and athletes involved, you are more comfortable betting on that sports.
Also, most of the time, if you have favorite sports, you will also form a "bond" to some athletes, like you will be rooting for them as if they are your friends.
