When I first started with sports betting, I honestly had no clue about the terms. I thought it was just about picking who wins, and that’s it.
Then I saw people talking about spreads, juice, parlays, and I was like, “what?”

For example:

Moneyline ..  this one I understood easily, just betting who wins.
Point Spread .. this confused me at first. I lost a few bets because my team won the game, but didn’t “cover the spread.” That’s when I realized it’s not just about winning, but by how much.
Over/Under .. also called totals, where you bet on the combined score. Took me a while before I got comfortable with this.
Parlay ... I tried this early on thinking it was an easy jackpot, but the risk is crazy. All your bets have to hit, or you get nothing.
Juice/Vig ... didn’t even know this existed when I started. Basically, the house edge that makes sure the book earns no matter what.

Now it makes more sense, but I wish I knew these sooner.

How about you guys? What betting terms confused you at the start? Any tips for newbies on which ones they should master first before placing serious bets?
