Ideological commitment and personal beliefs are orthogonal, much in the same way as religion and personal faith are orthogonal. IRGC members are ideologically committed, because they have chosen to serve the regime. They are committed, because if the regime ever fails, things will be bad to them personally.

Authoritarian regimes also understand that they need to keep their core supporters happy. If oil money dries up, everyone else will suffer before the IRGC. See North Korea for an example.

90% of IRGC funding comes directly from their own oil empire, without oil they barely have any funding. They can't make the other parts suffer before themselves here since they get it directly from owning the oil exports, it doesn't go via the government.

If they start trying to take money from the military then they would start the civil war themselves, they can't do that.

90% of revenue, not funding. Most of it is revenue from the businesses they run, and most of that goes to ordinary business expenses.

In any case, it's just an arrangement that has worked for the IRGC so far. If it stops working, the regime can make other arrangements. Such as extracting more money from the 90% of the population that are not particularly relevant to the continued existence of the regime.
