Very well said and I completely agree, and I also remember making an example that is somewhat related to this which you have said.
In one of my previous comments on this thread I believe, I talked about someone being sick and clearly needing to receive medication, people around can see that this person is sick and needs medical attention, but the person in question refused and insisted that he or she is not sick, treatment is not something that can be forced on a person except when that person is completely down and can no longer help him or her self up.
Same also goes with all forms of addiction, not just gambling addiction, just as you have said, a sick person have to first agree that he or she is sick and needs medical help, then he can either call the doctor to come check on him or her, or he or she can visit the hospital for check up and possible treatment, same goes with addiction, an addict who has refused to accept that he or she is addicted and need help, will likely remain an addict until he or she first agree, then seek help to come out of it.
Acceptance and willingness are the major key factors in recovering from gambling. It's essential for successful medication that the patient is well-aware about his condition and is willing to be treated and be helped by the professionals. After all, you must first help yourself. Gambling addiction is like a sickness that is serious and has to be healed, otherwise it will consume you and bury you. Anyone that doesn't want to be helped will not recover from their sickness. One must be determined to combat addiction by undergoing rehabilitation and medication together with the professional guidance and counsel. This way, there will be lesser chances of undergoing relapse.
