It is highly unlikely to be selected and a lot of the people that apply end up doing other things with their lives that takes them to the US through non immigrant routes (like I said above: studying, working, internship, etc) and in those cases they do not have immigrant intent because they plan to return to their country once they are done with it.if you don't want to submit ds260, then why take part in the lottery in the first place. Because even without ds260 they can still find your details in their system. US embassy can still find your name in their selectee system.
Simply applying does not show immigrant intent because you can change your mind, not get selected, get selected and decide not to proceed with it...
