Had Blood Drawn. Noticed That The Nurse Had Hole In Her Glove Also Blood Stain. Not Replaced From He Previous Patient. Chances Of HIV Infection?

Question: i would like to ask a question about hiv and std's. I recently went and had blood drawn at a labcorp and I noticed that the nurse or phlebotomist had a puncture/hole in her glove which she did not replace from the previous patient/patients. Now she had some red stain on her glove which could have been blood from the previous patient or it could have been blood from herself as she may have had a cut where blood had seeped thru her hole in the glove. so my questions are 1) if the phlebotomist did have a cut where blood seeped thru the puncture hole in the glove and she was in fact HIV positive or had some other std could she have infected me if she touched the needle and accidently put on the needle before going into my arm. Im worried about the thought of her contaminating the needle before injecting it in my arm; and 2) if the previous patient had HIV and got blood on the phlebotomists gloves and then touched the needle thereby contaminating the needle before injecting in my arm could I get HIV or any other STD? 3) could the phlebotomist have infected me by touching my puncture wound with infected blood on her gloves from herself or the previous patient..Im sorry for the length and detail of the questions but im freaked out bc the nurse/phlebotomist never changed gloves from the previous patient and seeing red stain scared me. thank you. I had asked Doctor's on the STD forum and was told I had posed my third question in 6months and therefore was told to come to the site. I would appreciate it if I could get some answers as I am on the verge of getting engaged and would like to be sure I am ok. thank you very much

Does this mean I can not get hiv or any std like hepatitis or any other bloode borne disease for example this way?

I'm a little confused w the word negligible I guess. I thought if the nurse accidentally touched the needle and contaminated that would be enough to infect me bc the Needle would have gone deep enough in the body to infect. Sorry to bother w my questions.
Thank u

Just one last question please and I will not take up any more of Ur time. I just want to make sure that Ur answers and responses are pertaining to the fact that the nurse did not switch gloves and there may have been blood from her own hands/fingers bc there was a puncture in the glove and also the possibility that it could have been the blood of an hiv patient before me?
