Yes.
Remember that we're talking MVP here, not production service. If your service makes it to the front page of HN and then crashes under load, you go to YCombinator or some other accelerator, say "We built a service, it was so popular that it got to the top of Hacker News and then crashed under load. Here's the demo link, and we have a list of X thousand users who signed up to learn more before it crashed." You will be accepted, and then you will have access to the $100K in Google Cloud's program.
The one exception is if they feel that you lack the technical talent to build a scalable system even with hundreds of thousands of dollars in funding. In that case, they will tell you "Go find an ex-Googler or ex-FBer to be your technical cofounder and come back to us." In that case, $100K won't make much of a difference, you lack some critical skills to employ that $100K well. If that is your situation, well, I happen to be an ex-Googler with experience scaling Google Search who is in the market for a new project. I have my own ideas but would be happy to abandon them for something with demonstrated traction, so I would be happy to entertain e-mails (my address is in my profile) with a demo link and a spreadsheet with X thousand user signups.
