Keep making mistakes my third week at a new job. Does this make me look bad?

Feeling embarrassed and defeated. I just started working at an investment bank in a really fast paced environment (24 year old).

I keep making stupid, little mistakes. I feel like a moron. Theyre just small slip ups and I should know better I am just learning so much at once it is overwhelming. I have never worked in a fast paced environment. Let alone remotely.

It is so embarrassing. Is this expected? Or am I doomed?
