Will number of user affect loading speed

Hi all…

I am very new with this bubble…with no coding experience…can somebody help to my question…(it may sounds basics to many of you😊)

Is number of users could affect speed of page and RG’s loading? It means if there is any difference when a few of users or a lot of users access the same page at the same time

I start building web app which may…when it grows…have thousands or hundred thousands of users registered.

Its something like a society management app, consist of some basic financial management for each of society cluster…member datas, forum, etc

Thanks in advance
