Well, I’d agree that people who do their research have a better chance of winning, but we can't deny the fact that it doesn’t guarantee winning. Why? Because it also depends on who is their opponent. For example, if two teams are equally skilled and with great records, no matter who we bet, our chances are definitely just 50/50. Research can improve our odds, but it doesn’t mean we have a 100% guarantee. At the end of the day, luck still plays a big role, and with some good analysis.

Besides, I don’t think any gambler would do this every single day. Most of us have jobs and other things to keep us busy, after all.
