android - Firebase realtime database structure in chat app

Question

sorry for my bad English level, I'm from Argentina.

I have the following messages data structure in Firebase:

"messages"
   "-KezmqXSdKCNFFA432Uc___-KfCEwklG_y3naRDIUiY"
         "messageDate": "20170620"
         "messageTime": "18:44" 
         "message": "Hi"
   "-KezFDSAADFASFFS3221___-KASDF32324SDFASD1FS"
         "messageDate": "20170620"
         "messageTime": "22:23" 
         "message": "How are you?"

Where -KezmqXSdKCNFFA432Uc, -KfCEwklG_y3naRDIUiY, -KezFDSAADFASFFS3221 and -KASDF32324SDFASD1FS are users.

My problem is that I created a childEventListener in "messages" node to receive new users messages but I am receiving all the new messages of all the users (I'm logged in one user per app) because my childListener is in "messages" node.

Is it correct that if I have 1000 users when adding a message, a new message reaches the 1000 users? (Assuming that within the app, you can check to which user that message belongs).

Thanks!
