Yes but phobias can be overcome, i.e. challenging our conditioning. I did just this!
I was staying overnight at a country cottage. The bed I was allocated had a huge spider very high above the pillow area, on the ceiling! Then and there I knew I had to come to terms with this if I were to sleep. I asked myself what I was afraid of. Simple - that it would land on my face! I then asked myself had this ever occurred? No. So I overcame it with logic!
When I see a spider now, e.g. crawling on the floor, I employ the card and glass trick - capture it and fling it outside. No reason that they should lose their life just through a silly, learnt fear!
