I don't think there's any issue with relying on sources for our bets but when we OVER rely on sources it becomes a problem. It has no bearing on anything negative apart from the fact that it won't make us knowledgeable in what we're doing or betting on. This is where you get to find someone who has stayed in an industry for years, yet they don't know basic things about that industry.

Whatever we overdo in life generally often becomes problematic for us. It's the same principle of begging people for fish when we can fish by ourselves if we put our minds to learning and acquiring the needed skills for fishing.

Every gambler/bettor should at least learn the basis of their game. What if the sources dry up tomorrow, it means they will be rendered useless. It's the same thing that happens with those who rely on trading signals to place their trades.
