Depends on the kind of blur. Some kinds can indeed be almost perfectly removed if you know the used blurring function, others are destructive.
But, yes, don’t take that chance. Always delete/paint over sensitive information.
Source: we had to do just that in a course I took a long time ago.
wouldn’t you also need to know in what kind of pattern the blur was applied. I am sure if you do it multiple times starting from multiple non identical partitioning of the region, it will be impossible.

I prefer sampling the surroundings, typing out a different number or text over it, then blurring with a non destructive effect.

You’re severely underestimating the power of weaponized autism.
Ah man, I remember when they caught some pedo creep who used a non-destructive blur on the CSAM materials he produced with his face. So satisfying.
He only spiral blurred his face… So they just did it in the opposite direction. It was beyond stupid
