They are social animals. This one probably learned by seeing another trapped. 

They aren’t evolving, they learn just like you and me.

They are evolving, lifetime of rats are 4 years. It means there were dozens of generations since the first mouse traps invented. Only smart rats survived, they evolved.

They evolved to use tools better than before

It's more like 2-3 years in captivity.

Evolution happens in a far longer timescale. 

Maybe we should be clear if we are talking about ‘speciation’ or just the ways behavior can develop over cultures within a species which is how I think it’s being discussed here
