how does bitcoind functions in bitcoin exchange model?

i mean exchange allows every users a unique BTC deposit address

different users sends btc to different addresses but BTC endsup in same wallet

can i create multiple receiving address by bitcoind (getnewaddress) or i will have to use HD wallet for that for our users (we are building lotto system on bitcoin)
