會2 is a learned skill that fits the hand now (我會游泳 — I can swim). 會1 reads the odds of a future event (明天會下雨 — it'll probably rain). Same graph: 會2 faces a trained ability, 會1 faces a likely outcome.
會 is know-how acquired by learning (我會開車 — I learned to drive). 能 is raw capacity or permission in the moment (我喝了酒,不能開車 — I drank, so I can't drive). 會 asks whether you ever learned; 能 asks whether you may or are able right now.
negating with 沒: 我沒會游泳 → 我不會游泳
using 能 for a learned skill: 我能說中文 → 我會說中文
using 會 for in-the-moment ability: 太晚了,我會回家嗎 → 太晚了,我能回家嗎
English 'can' covers learned skill, raw ability, and permission with one word, so learners reach for 會 where 能 is wanted, or for 能 where 會 names a trained skill.
