77% of the tickets and 79% of the money is on the 49ers ML

It's simple. If you are betting the 49ers you would bet the ML. If you are betting the Chiefs you would bet the spread. Those numbers are not surprising at all.

Do you not understand that sports books have a vested interest in lying to you..?

Wake up Pollyanna!

lol..Yeah, I was a local for about 30 years... He cracks up when he gets off the phone with you

The main technique bookmakers use to put the odds in their favor is the inclusion of vigorish (aka Vig). It is built into the odds bookmakers set to help them make a profit. In essence, it's a commission charged for laying bets. To best explain vig, let's look at a simple coin flip.

The toss of a coin has two possible outcomes, and each is equally likely. There is a 50 percent chance of heads and a 50 percent chance of tails. If a bookmaker were offering true odds on the toss of a coin, they would offer even money. This is 2.00 in decimal odds, +100 in money line odds, and 1/1 in fractional odds. A successful $10 bet at even money returns $20, which is $10 profit plus the initial stake back.

Let's say a bookmaker had 100 customers all betting $10 on the toss of a coin, with half of them betting on tails and half of them betting on heads. The bookmaker would stand to make no money at all in this scenario.

Now, with the inclusion of vig, a sportsbook is guaranteed to make money regardless of the outcome. When two outcomes are equally likely, it is common for them to use odds of 1.90 (-110 in money line).

Continuing with the coin toss example, the odds-on heads and tails would still both be the same, but they would now be at 1.90. This means that a successful $10 would return a total of $19.09 ($9.09 in profit, plus $10 original stake).

As you can see, the change in odds makes a big difference, and the bookmaker is now making a guaranteed profit on every toss of the coin. The total amount they pay out is always going to be $954.50 against the $1,000 they have received in total wagers. They have found a way to make a profit margin of $45.50 on the vigorish.  

This is a very simplified example, but it' just goes to show you how bookmakers set the odds to give them an advantage. Things get a little more complicated when it actually comes to sports events, as the possible outcomes aren't usually equally likely. This is why you have to pay a premium on point spread lines that land on key numbers. Sportsbooks are simply protecting their bottom line and doing everything in their power to make sure the action is equal on both sides.

And "everything" includes lying to you-  The ML hasn't moved- That means they are getting equal action guys
