Everything in the universe could be predicted if you knew all of the initial conditions and all of the laws of physics.
Ignoring the computational impossibility (storing the information of the universe in the universe but still having the universe exist, and then calculating for however long...) then if the universe worked on Newtonian physics then maybe, and even with what I am about to say then such knowledge or even a limited aspect of it would allow for some incredible things -- every human might be a unique snowflake but psychology still has its uses. With quantum mechanics then no -- quantum tunnelling, spontaneous atomic decay, general radioactive decay Brownian motion... all would utterly break that notion. Much like disease is not magical any more and is instead often laid at the feet of bacteria, viruses and parasites (among other things) I suppose I can not rule out it being the results of something far smaller ( http://htwins.net/scale2/ ) but if you are going to make examples like those of dice then you at best need to refine your examples.
I forget where it was first mentioned to me (probably a freakonomics podcast) but a quick search brings up the material in question -- https://victorianist.wordpress.com/...freedom-the-bicycles-impact-on-1890s-britain/But I do believe that the person you end up marrying is pre programed.
Short version is the invention of the bicycle dramatically increased the distance that someone might meet a potential partner over. In more recent times there has been a lot of study on online dating websites and what makes them work, or indeed fail and the general failure of anything to truly take off in Europe (something people usually put at the feet of language issues). That would rather damage such claims.
Somewhat less cynically if you want to do the fated (fatalism?) approach then fair enough. It would rather excuse a lack of effort and a lack of active measures. I will leave it there though as we do not need me being cynical in another thread.
