At-the-Money
At-the-money (ATM) describes the rare circumstance in which the price of the underlying stock matches (or is within a few cents) of the strike price of the option you hold.
In-the-Money
Let's say XYZ stock is currently selling for $18.34 and the nearest strike prices are $17.50 and $20.
If we decide to buy a call option and choose the $17.50 strike price, our option is considered in-the-money.
This means that our option is already profitable. And by purchasing the option, we gained the right to buy the stock for $17.50 per share and can turn around and sell it for $18.34.
In-the-money options typically cost more to purchase, but can result in a higher delta.

Out-of-the-Money
Using our XYZ stock example trading at $18.34, if we were to buy the option with a $20 strike price, we are immediately in a loss position and have purchased an option considered out-of-the-money.
We have the right, but not the obligation, to buy the stock from an individual for $20 per share, but can only sell it for $18.34.
Since we are buying the option in a loss position, its value is considerably less than an ATM or ITM option. The delta is also considerably lower.
