Inflammation really depends on the person, right?

Some people smoke even before getting their splint removed after surgery and still do not get inflammation, and I am a nonsmoker, but honestly after surgeries or procedures so far, especially after getting Botox or filler, there were many times I drank alcohol that same day. I did not even pick up the antibiotics prescribed by the hospital at all (for procedures only). When I had surgery, for my first nose surgery I abstained from alcohol for a month, and later when I had artificial dermis inserted and the silicone replaced to adjust the nasal bridge or nasal tip (this was closed rhinoplasty), even though I drank alcohol after only a few days while still taped up, I have still never once had inflammation. An inflammatory reaction appears when the body recognizes something as a foreign substance, right? If people have surgery at the same hospital, with the same materials and the same surgical method, can one person get inflammation while another person does not? I had revision rhinoplasty this time, and it is still day 5 so I still have the splint on, but maybe because it is a revision, I suddenly started worrying about inflammation, something I had never worried about in my life. The hospital where I had surgery is fairly famous, but after surgery I searched a bit more, and I saw a few people who said they had surgery there and got inflammation.. Inflammation and contracture really are case by case, right?
