Are the RbxLibraries modules, and is LoadLibrary like require?

This should be a pretty simple question to those who know, but i ask this because i can return their individual environments with getfenv. So, is LoadLibrary like saying require?

Comparison:

Module:

local t = {}

a = 1
b = 2

t.test = function() end

return t

Script:

-- This script is inside the module script

local env = getfenv(require(script.Parent).test)
table.foreach(env,print)

-- Output --

-- a 1
-- b 2
-- script ModuleScript

And the same effect happens with LoadLibrary:

table.foreach(getfenv(LoadLibrary'RbxUtility'.Help),print)

-- Output --

-- Encode function
-- Decode function
-- Null function

So, that's pretty much it. It just seems to me that LoadLibrary is like another way of saying require, except it's parameter is limited to the string value of all it's library names.
