Sports Betting with ChatGPT

I’m visiting family in Illinois this weekend, which means we can sports bet. I made a GPT with access to weekly NFL Player Stats: https://chat.openai.com/g/g-vxtiCaEDN-fantasy-football-stats-cruncher

Today I used it to help me make (semi) informed sports bets on the days games.

Travis Kelce

Travis Kelce to score a TD estimated at 66% likelihood of No, and 44% likelihood of yes.

What has he done previously?

Hmm, seems like 67% chance of not scoring a TD to me
This data point tells me nothing
Ahh the context I needed

So the odds were set slightly below his historical probability for this season, and on top of that, he is playing a good Def. Seems like the Swifties may be betting with their hearts.

Lamar Jackson

Lamar Jackson Passing Yards are set to a 53% odds scenario no matter if you choose over or under
He’s gotten more than 211.5 yards 53% of the time
KC has let up 211.5 yards 53% of the time

So it’s two 53% scenarios? How does that work? Is the bet right on? Do I multiple them? I’m not sure, but I’m just going to take the over because even a square bet is a pretty good bet in sports gambling. Wish me luck!
