Small holes are genuinely easy. What's hard — and what gives patches away — is making the repair disappear into the wall around it. That part is about technique, not the size of the hole.
Match the patch to the hole. A nail hole just needs a dab of spackle and a light sand. A hole up to about 2 inches (doorknob size) is a good fit for a self-adhesive mesh patch or a press-in plastic patch. Anything larger needs a cut-in piece of drywall, screwed to a backing strip or furring piece behind the hole, which is where the job starts asking for real skill.
Where patches go wrong
The order that works. Cut and set the patch → tape if there's a seam → first coat, wide → sand → second coat, wider → sand → third coat, feathered out → sand → prime the patch → texture to match → paint the full wall section, not just the patch, so sheen stays even.
Where someone experienced earns their keep. Anyone can mud a patch. Feathering it thin enough to vanish and matching a texture you can't quite name is a feel you build by doing it a lot — the exact kind of thing that's worth having someone show you once, on your actual wall, instead of guessing from a video.
