No. Many people work their entire lives trying to keep on top of bills; others spend their entire lives saving for a retirement they may not live to see. So if income was no longer a concern, I'd quit tomorrow & focus on what to do with the rest of my life. Some of that time would be spent pursuing interests & hobbies that I never had time for. And if the amount of money I won was more than I could reasonably expect to spend in one lifetime, I'd also be spending time on how to make that money work best for local charitable institutions. Also, you said "when you remove financial motivation what else is left?". If you're only motivated to improve your own situation then, yeah, sure, I can see one's motivation evaporating by winning the lottery. But if you see it as an opportunity to help not only yourself, but others as well... well, there's a lot of people out there that could use a helping hand.
