What is this elitism among pure science people?

In my (19 F) college, the mathematics and physics majors consider themselves the "gods" ( or something equivalent). They consider every other major stupid and judge them with all their heart. If you tell them you are studying computer science, they will judge you harshly because you have "sold" yourself for the "hunger" of money.

I am so done interacting with them. However, they are also the ones I must engage with due to the many common courses I am taking this semester (I am studying Algebraic Number Theory and Topology-1, along with a few other Computer Science courses). Almost all the Mathematics majors I speak to always joke about me being dumb (and to be fair, academically I am not; I am actually the third-best in the class, if we judge by grades and I know they are not the best factor). In fact, whenever they ask for my score and realise I have scored higher than them, they end up cursing themselves for scoring "less" than me, a Computer Science major.

Does this improve as everyone gets older or will it stay forever like this? I hope I am not over reacting but I absolutely do not feel this is nice and I feel it is pretty toxic. I have also seen professors making such jokes. I have been considering double majoring in math and CS, however, if this is how the math community is in general, then I would absolutely not like to indulge with them.

Can people share their thoughts on this? Is this true in every university? If yes, I would most probably not consider doing math PhD as for me, community and support matters equally to have a sane mental health.

P.S. I am not sure if this is the right subreddit to post. I did go through the rules.

EDIT: Woopsie, I did not expect this post to receive so many replies. I am really grateful to every one of you for reading and sharing your experiences with me. I understood that what I am facing is a bit severe but still something which is common in almost all departments. Many recommended to ignore such people and talk to ones who are much kinder ( which does exists). I trust all of you on that statement.
