Sampler object names returned by a call to glGenSamplers
are not returned by subsequent calls, unless they are first deleted with glDeleteSamplers.

are marked as used, for the purposes of glGenSamplers
only, but they acquire state and type only when they are first bound.

glGenSamplers
is available only if the GL version is 3.3 or higher.
