AIDS is not a "symptom", it's a medical syndrome.

A medical syndrome is a set of medical symptoms that are usually (although not always) caused by a single disease pathology.

In the case of AIDS, it is only caused by HIV infection and progression to the point where specific cells of your immune system (CD4+ T-cells) fall below a critical threshold.

Also someone who has HIV and develops an opportunistic infection has progressed to AIDS regardless of CD4 count
