Please somebody answer

Hello, I read somewhere that "Drug resistance can cause HIV treatment to fail", it is exactly a line I found there. I'm seriously concerned about it: Did they mean all HIV treatments (I mean every HIV treatment/drug/class of drug/therapy available today)? or a an HIV treatment (a particular drug or class of drug)? Is there any theoretical/practical evidence that proves a drug resistance HIV (any kind of resistance) can cause literally every treatment or drug available totally 100% useless and ineffective like the new coronavirus?
Can someone with this kind of resistance become completely hopeless and untreatable? I searched google so many times and asked many experts yet no one gives me an answer. Last time I gave HIV test was only 3 years ago (it was negative) but I'm really terrified if I am infected since then and developed such a resistance.
