Looking around, it does look like she's explained things better in other videos than the one I saw, so maybe I was too harsh.
The video I saw at the time is "Why is quantum mechanics weird? The bomb experiment" where she describes entanglement as a photo being torn in half and then sent apart, and then vaguely says that it is a "stronger" correlation than that.
On looking for that video though, I watched "What did Einstein mean by “Spooky Action at a Distance"?", where she describes things a bit more thoroughly with socks, where she explains that the correlations were created locally but when you measure the one particle on one side the other particle's wave function changes. She then goes on to actually explain that the sock explanation does not work as it does not sufficiently create strong correlations, which I think is a much better explanation
Looking back, I think I've learned a lot more about quantum physics since I last watched her videos. Back then, I think I saw her repeated use of explaining entanglement as a "stronger correlation" to be a cop out. Now that I've dove into the actual Bell Inequality experiment and understand how it works, I actually quite like that description as a placeholder for a very strange phenomenon that none of us really understand yet. Still, I do think she should have clarified just a bit better on the first video I mentioned, but I guess when you make lots of videos on one of the most complicated topics of all time it's rather easy to omit a crucial detail here or there.
