ELI5: If a mosquito sticks his "needle" into someone with AIDS, then into someone who doesn't have AIDS, why doesn't the second person not get AIDS as well?

Wouldn't it be almost identical to sharing a needle with someone who has AIDS? Other blood-based diseases spread with Mosquito bites, so why not this one?

Very few blood-based diseases spread via mosquito bites. The main one is of course malaria, but the malaria parasite is an organism that actually needs to be inside mosquitoes (as well as inside humans) to live.

HIV, the virus which causes AIDS, cannot live for long outside of a human body. What's more, mosquito bites aren't really like an injection from a doctor -- that they're not putting anything *into* the bloodstream, rather they're taking blood out of you.
