This might be new for some who just gamble without a real bankroll, but for those who are serious about sports betting, consider this: data is crucial for tracking your journey. According to a site I found that also shows a good format for spreadsheet tracking, here are the benefits of keeping tabs on your bets.

1. You can find what bet types you excel at. By tracking your bets, and grouping the data by bet type (spreads, totals, moneylines, props, parlays, teasers) you can quickly find out what types profit you the most, and which ones cause you to lose your bankroll to the books.
2. Learn what leagues you profit from the most. This is a big one, and although you probably have a good idea of what leagues you're best at, grouping your bet data by league can greatly improve your chances of figuring out exactly what is causing those wins on your NFL bets, and causing those big losses for NHL bets, for example.
3. Spot any favoritism or biases you have. I spoke with a semi-pro bettor named William after the 2020-21 NBA season. Will told me that after the season, he broke all his tracked bet data down by team and compared it to the research he had done before he placed each bet. He realized that there were at least 15 times he lost a bet where his research had pointed him to bet on one team, but his favoritism caused him to bet on the opposite team! Crazy right? Think of all the biases that could be keeping you from making the right decisions.
4. The ability to follow your money. By this I mean knowing where your money is going, where you are putting the most in, where you are losing the most, and what areas you are profiting the most
So, sports bettors, has it ever crossed your mind to keep a spreadsheet?
I like to gamble, but I never thought about becoming a professional gambler because I think it's quite difficult and even impossible to happen, I don't know what kind of professional gambler you mean, whether it's those who can win consistently by always succeeding in making a profit, but that's also impossible because if it were like that, maybe many people would have made gambling a source of income.
With those who are rich, gambling which certainly uses a large amount of bets, are people like this who are professional gamblers, I don't know for sure but occasionally I see people who are silent for a long time and then place a bet and can win, but I think that's just because luck is on their side not because they are good at predicting.
