Does the Warlock's Expanded Spell List from their patron only add it to their list of options, not their spells known?

Question

Expanded Spell List
The Fiend lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Should this mean, that unlike the Cleric, a Warlock does not gain the Patron spells in addition to the spells known?

So a 1st level Cleric with 16 Wis can prepare 4 spells, plus 2 from the Domain, but a Warlock only knows 2 spells, no matter what?

Answer 1

Yes

As it is stated in the text:

Expanded Spell List

The Fiend lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

I.E. whenever you learn a spell, you have extra choices. You don't have extra spells known.
