It's surprising that we find ourselves in a universe which does appear to obey certain laws. There's a whole bunch of assumptions made to help us understand how things work and it turns out they're mostly correct. i.e. It's more astounding that we CAN understand the universe and how well maths can act as a model/language to understand it.
Not that surprising. A universe without predictable laws would be unlikely to host life. I mean physics really only knows how to do statics and oscillations and those things work because many systems are at equilibrium or just slightly perturbed from it, probably because of the mysterious low entropy condition which defines the past.
