The application of jizya varied in the course of Islamic history. Together with
kharāj, a term that was sometimes used interchangeably with jizya,
[21][22][23] taxes levied on non-Muslim subjects were among the main sources of revenues collected by some Islamic polities, such as the
Ottoman Empire.
[24] Jizya rate was usually a fixed annual amount depending on the financial capability of the payer.
[25] Sources comparing taxes levied on Muslims and jizya differ as to their relative burden depending on time, place, specific taxes under consideration, and other factors.

I would imagine Ottoman Empire wouldn’t have gotten their main source of income from non-Muslims if it had been one dinar a year.
Your somewhat rosy description sounds more of idealized version what it might have originally meant to have been than what politics made of it later.
