They prefer them under Dhimmi status right?
Kinda sorta not exactly. IIUC, the _jizya_ -- the poll tax on non-Muslims -- wasn't a big moneymaker for the Ottomans. Rather, they prohibited most non-Muslims from joining the military, then taxed people who didn't in lieu of military service.
Also IIUC, civil servants above a certain level were immune from most forms of taxation. Which provided a powerful motivation for members of religious minorities to join the civil service, if they could. That's why by the years around 1800, most ministers and senior bureaucrats were Christians, most commonly Phanariot Greeks.
Also, none of this applies to the last 50 years of the Ottoman Empire. They got rid of most formal, legal discrimination in the 1840s and '50s; by the time of the Balkan Wars, there were small but significant numbers of non-Muslims serving in the armed forces.
