If you have a "luck elixir" active, there is a fixed percentage chance that you will get to roll twice. If you see "Feeling lucky....", then this second roll occurs. The system will then give you the better of the two items; by "better", it only looks at rarity: Trash (gray) < Common (white) < Uncommon (orange) < Rare (green) < Legendary (purple) < Epic (pink). if the two items are the same rarity, it will give you the first item you rolled -- it does not distinguish "better" within a rarity category.

When you do get the item from the second roll, that is when you see the "You ARE lucky" message.

Note that those who bought (and are wearing) the "Big Luck" vanity helmet for St. Patrick's Day have an effect similar to the elixirs, but with a much lower chance of getting a re-roll.
In fact, that does make sense.

"Feeling lucky" means you re-rolled, just not for better loot.

While "You ARE lucky" means you re-rolled and did get better loot.
