Generally not. SSH tunneling is generally used for a single app, where
VPN is used for all apps. Note that if one really wanted to, you can
tunnel PPP over SSH making a sort of "poor mans" VPN.

It creates a transparent "tunnel" that makes your machine look and act
like it is on the network at the other end of the tunnel.

Yes, one connects a machine to a remote network (client to server) and the
other connects two whole networks together, creating one logical network
(gateway to gateway).
