It doesn't matter what genre of beats you make, the 808 is one of the most powerful instruments as a beatmaker. Now, the 808 sound is a VERY SPECIAL instrument because it's like a hybrid between an kick drum and a bassline.
To become a GOOD producer, you NEED to learn how to use an 808, and a bit of its history. Each genre uses the 808 a bit different, but it's a key element for fullness in your beats.
(The 808 kick drum originally comes from a Roland-TR 808 Drum Machine. There's also many other common sounds we hear in popular songs all the time from this drum machine, but the 808 is known for its initial hit [similar to a short-tailed drum], then it's long tail which rattles the subwoofer [like a bassline]).
