Am I in danger of something serious if I get a tattoo?

Good morning, recently I did the first tattoo, opened a new needle and tube with me from sterile packaging, apparently uses disposable, for each separately such a set. She pulled new gloves out of the box and dressed. Wrapped had these preparations all in foils, while the gun and armchair was not offered, (only there was disposable paper planted new next to me) of which I realized the next day, as I thought about it all.. I asked this tattoo artist how she prepares these things, she says she always disinfects the razor as well as the chair.. I was terribly scared and still afraid of how I would think about it.. Am I really in danger of something serious? The tattoo is well-re-played so far. Please hint, I know it's not about drugs.
