ELI5: Why can mathematics and physics simulate natural phenomena so closely in thought experiments, calculations and computer programs?

Because mathematical and physics models that do not correspond closely to reality are deemed incorrect and not used, then the scientists get to work trying to fix what is wrong or looking for a new approach. Your question is quite like asking why a car is so good at travelling on roads: because the attempts at building a car that resulted in something that really sucked at travelling on roads are simply not selected for mass production.
