Full nodes are important in maintaining the continuity of bitcoin network, they check and validate transactions, making the network secure and invalidates invalid transactions. Most wallets are light clients called simplified payment verification wallet that connects (synchronizes) with central server (host node).
The central server can link addresses on the same wallet together, link IP addresses, know the total balance addresses on a wallet is holding, making privacy not to be possible. Some people make use of Tor for anonymity, the central server can still link addresses together, know the wallet balance but in a way the IP address is not known as the user is making use of Tor. This makes anonymity to be possible, but yet no privacy as addresses and balance are known through the central server.
Some people can have several wallets, making use of just one (or two addresses) on each wallet, rerouting Tor connection on each wallet in a way different Tor route locations are used to connect to each wallet as making the connection not to link different wallet address together. This can help privacy, but in just a bit and mistake of rerouting can occur, and still also depending on central server, unlike running full node using Tor connection in a way you do not depend on central server as you have your own node which makes privacy to be possible.
