You choose which one. Lucky (Feat): 3/day you can have "not-Advantage" on your rolls, or "not-Disadvantage" on an enemy attack. The general rule I have in mind is the one that tells us how advantage and disadvantage work ( PH , 173). ... the difference is Lucky vs Disadvantage. Yes, the Lucky feat can counter a natural 20, on an attack roll.
For example, a rogue using the Lucky feat still can't sneak attack with disadvantage, even though they get to pick the best die.
You can also take the Elven Accuracy feat, which can give you a boost to your Charisma and extra rerolls whenever you have advantage.
Dungeons and Dragons (D&D) Fifth Edition (5e) Feats, A comprehensive list of all official character feats for Fifth Edition.
You are at disadvantage at all Arcana, History, Medicine, and Nature checks. The specific rule is the Lucky feat, and we know that a specific rule trumps a general rule if they conflict with each other ( PH , 7). This is especially useful for Shadow Sorcerers, since magical darkness will give you advantage a lot.
Of course, Lucky is a good feat for literally any character. Tides of Chaos (Wild Mage): gain advantage when you need it.
However, according to Jeremy Crawford in his tweet you would roll 2D20s for Disddvantage + 1D20 for Lucky, and then either keep or remove the lucky die. 5e Core Feats Here we present you with the online and comfortable selection of core feats in D&D 5edition. @JeremyECrawford Pls expln Lucky Feat from Sage Advice. How is that still disad?
"If a DM wants advantage and disadvantage to play their normal roles even when the Lucky feat is used, here’s a way to do so: roll two d20s for advantage/disadvantage, roll a third d20 for Lucky, eliminate one of the three dice, and then use the higher (for advantage) or lower (for disadvantage) of the two dice that remain."
You have 3 luck points. This is ok, but why not take some feats that help outside of combat (and can be useful in combat). Lucky You have inexplicable luck that seems to kick in at just the right moment. The intent of the lucky feat, as described when you use it on one of your own rolls, is to wait until the first die is rolled.

If that was all it did, negating up to three crits a day (note it can't be used on enemy skill checks or saving throws) it wouldn't be particularly noteworthy, and most people wouldn't even bother with it. With lucky, the dice are rolled serially.
Whenever you make an attack roll, ability check, or saving throw, you may spend 1 luck point to roll an additional d20. And then from the combined 3(or 2 if you decided not to use the lucky die) you pick the lowest die. Disadvantage is when dice are rolled simultaneously. It's similar to Disadvantage in that way. I’ve prefaced many an article with how well-balanced I think the 5e rules are, and the more I play, the more I realised how spot on WOTC got things… well apart from Counterspell, healing rules, Paladins (in particular their divine smite ability), and a few other bits and pieces..
