But only if you want uniform randomness, for many simulation
purposes the distribution needs to be weighted according to
some non-linear distribution. For example, when we wrote a lot
of network simulators we used Erlang and Poisson distributions.
And for pink noise simulations we used Gaussian distributions.

You can of course produce those by filtering/weighting the
output from a linear distribution but in either case you need
to test the relative outputs at sampled slots along the range
to ensure the output fits the curve.
