Jupiter's core is a fuzzy core, not a solid core. It has a bizarre magnetic field and the NASA probe that was there or near there in 2017 confirmed that it has a core (as opposed to the theory that it has no core at all). But it's not solid (as was another possible scientific hypothesis). The discovery by the Juno spacecraft was ultimately an unexpected one and the spacecraft was able to help scientists dismiss or debunk several theories regarding the planet. Large regions of Jupiter are non-convective. And in addition, Saturn may have a fuzzy core too.

Just summarizing what I got from the video.
