Im male i had anal hpv warts from 8 years ago , it's still just one wart (as i seen from outside) im scared from getting cancer specially when i heard a doc on youtube he said "90% of gay people they came to me with anal warts they got anal cancer) ?

The genital wart strains are not linked to cancer. However, the sexual practices that bring exposure to wart strains will also expose one to the non-wart high risk strains associated with cancer. There are no obvious signs that they were exposed to or acquired a high risk strain. Getting the HPV vaccine prior to exposure can reduce risk of acquiring a cancer strain.

Please keep in touch with your doctor. PAP smears of the anus can and should be done, as is done to prevent cervical cancer. You should get HPV vaccine to avoid infection with other strains of HPV.
