Well Azerbaijani army numbers approx 50,000. So far they have sustained close to 7000 casualties. Injuries are usually 2-3 times higher atleast.
So there's a good chance that Azerbaijan has now lost one third to half of its fighting force to death and injuries.
Keep in mind Azerbaijan is refusing to acknowledge any casualties and Aliyev is refusing to accept corpses as well.
If you look at the gains that Azerbaijan has made, it's obvious that they would have to lose their entire army to take the entire enclave. So basically it's not really feasible. So basically without Turkey Azerbaijan would not have made any real gains at all.
Keep in mind. Russia has a military alliance with Armenia proper so Azerbaijan cannot attack Armenia and the Armenians will continue to send in re-inforcements and Russia is supplying Armenia will a constant supply of weapons. Iran is also supplying some equipment but to a lesser extent.
Also keep in mind winter is approaching, so let's see what happens. There's a good chance that Russia will supply Armenians with lots of winter equipment while Turkish mercenaries could very well freeze to death, but we'll see how the Syrian mercenaries fare when it snows.
