Its all tout speak.
before the internet, the touts sold "inside info" on their infomercials. Then when peopel got smart to that scam, they sold handicapping and ability to figure out which team had an edge based on thousands of games worth of data.
Then when guys all got the same data touts had to change their approach again. Then it was back to inside info. Which as it turned out was pretty factual considering how many schools were cheating. At least in the NCAA stuff. But they still couldnt win consistently enough for people.
So then they took their math and started selling varience, using the
odds and changes to predict what guys were betting what way and then they evolved that into the so called originators versus steam chasers versus stale numbers guys. And that spawned its own genre of touts and forum warriors.
The only way to make money consistently betting sports is to play both sides with an edge, which right now is nearly impossible. You can try and beat it betting one side but to do that you have to pretty much get the very best number every single bet you make, which is almost as impossible as picking the right side in the first place.
Baseball is the easiest sport to make money at (aside from maybe WNBA, but the limits in the WNBA are so ridiculous that it is laughable) but at least in bases you can roll a few bucks over a couple times and make something somewhere near respectable in the 9 months you have.
But once football starts guys will piss it all back again because the NFL is basically the biggest sucker season ever thought of. Yet guys think it is somehow their answer to riches. Pretty much the only way to make money in the NFL is to bet maybe 10-15 games a season for massive amounts and hope you go 90%. Trying to grind it out with so few games is a joke, and the so called variances and edges are meaningless with that few games played. by the time you think you have it figured out the season is over.
But it is the big time sports betting sport so it isnt a secret it is also the one where the books clean up and they actually start getting enough post ups to pay back the guys they have been slow paying all summer.
