Meaning of the -110 number that is showing next to my bet?
Oddsmakers are putting a tax on each bet. This tax is known as the vig or juice. Vid is the short form of vigorish. The juice is the commission which you would require to pay to the sportsbook to accept your wager.
Duke blue devils are having -5(-110) which also means that if you want to bet on the duke as a 5-point favorite then you are at the risk of 110 to 200 dollars win.
The juice is considered as a positive number like Penn state -7(+110). This means that when you are betting 100$ on Penn state then it is a 7-point favorite and it will cover your win of 110$. If you are losing it then you will lose only 100$ which is a risk.
You always have to risk more on the favorite so that you can win on the underdog otherwise the sportsbooks will be out of the business.
