Sorry, @VeniceKing, I’m assuming you’re signing into Zoom with Google? I’ve never actually run into anyone that uses Google to sign in, and so my experience here is limited (non-existent is probably more accurate!).
While I can’t find anything in the Zoom Support articles that says this is the case – I’d have to assume that if you’re logging in via Google, Zoom uses that for your profile picture. I can’t find anything that would indicate you can change that – except perhaps changing your signin to an email address.
Take a look at this Zoom Support article on changing email addresses, which also has some info on logging in via Google and other services:

Most of the help you get from the Zoom Community is from volunteers like me. If you’d like to investigate further, you can submit a Support Ticket directly to Zoom Staff at:
