Disabled against the context of "normality".

You can function obviously, but not as society expects you to or even in way they can understand. For that reason, you receive the label of "has a disability".

The term "disability" is unfortunately as much a reflection of societal norms as it is genuine medical diagnosis.

Exactly. Luckily society seems to be slowly becoming more accommodating and understanding, but there is a long was to go before society truly understands how to value the contribution of people who are different. Seeing 'disability' in this way, it can even apply to traits like introversion (depending on the culture you live in).
