You're not engaging what I said at all. Do feel free to try again.
What you're claiming is patently false - D&D 5E defines 3 types of rolls as the core mechanic, and they differ only slightly
Attack Rolls
Saving Throws
Ability Checks
2 of the 3 are combat focused. Sure, they're in different chapters... but they are the three most common rules interactions, and they're all 1d20+PB+AttMod if proficient, 1d20+AttMod if not proficient. What differs are the 1's and 20's effects.
Most PHB spells are combat focused, some of which have non combat uses. Similarly feats and class abilities.
The other two claimed pillars of play are not mechanicalized well in the classes, feats, nor spells. Much of the playtest feedback revolved around combat balance.
Given all those, claiming D&D 5E isn't combat focused seems rather disconnected from reality.
The intent can be inferred by the competent English reading individual - the intent was to have social there as a backup in case people are dump-statting Charisma. Exploration is intended to lead to exciting combats. Combats have the most detail, and the most mechanical support, so many are going to use what they have been given...
Can one run a zero-combat D&D game? Sure - in any edition, even - but that doesn't make it not-combat-focused.
It does, however, leave out half the spells, and the main purpose for the Fighter, Barbarian, and Warlock classes to exist in setting.
