Both, actually. And of mechanistic statements. For example, if you have this sort of multiplicative central limit theorem with no lower bound, where you imagine independent variables being multiplied together - the attractor of that dynamical process, the result of that universal phenomenon, is lognormal. Add a lower bound, bam, power law (champernowne 1953 "A Model of Income Distribution"). So you're really making different claims about reality.
