it is the style of a dual coil pick up. Your bas probably had plastic pick up covers, if you were to see it off, you would see two rows of pick ups or the magnets.
Humbucker is the TYPE of pick up, there are many that are better then others. Some basses do come with good pick ups, others are going to be economy pick ups.
I do not know what your pick ups are, or what the alternatives are, but chances are they could be upgraded, and, depending on what you upgrade with ,and what you are wanting to get out of the bass that you want new pick ups to get will determine what you want to do with them.
Many people upgrade their pick ups, on any bass.
Other people do not upgrade them ever and do just fine.
I am upgrading one pick up on one of my stingrays to test out, based on the recommendation of a friend who is a stingray enthusiast as well, and he’s says the difference with the pick up that I am putting it, to the one that is stock is night and day.
I am putting in an Agiular stingray pick up.
He also said that the Seymore Duncan pick up for stingrays hardly made a difference. And that is not to say that Seymore Duncan pick up are pad, they most certainly are not, but in a stingray, they don’t seem to make a bid difference. but many people like that brand for other basses / guitars.
its another rabbit hole you can jump down, or not…
