Sort of. You can test a hypothesis that this is being generated by some nonrandom process and determine with arbitrary confidence that that hypothesis is more likely to be true, which is effectively the same. It's also possible that what we observe to be gravity is a 50/50 random process that has happened to always cause attraction when observed, but it would be so astronomically unlikely that it isn't worth considering.
