Probability: highly unlikely.
Speaking for Europe, I see a lot of silent innovation. No press, no LinkedIn posts, not an article on their website. There are a lot of US firms that shop in Europe for high tech. (I know of instances were the US company buys the IP from the EU supplier + take public credit for it + forbids the supplier for showcasing their success in public.)
What is different is:
1) the amount of money available in the US. The US enjoyed a very beneficial position post-WOII, enabling them to run high deficits.
2) the US has a positive attitude to entrepreneurship. You are not a failure when your company goes bankrupt, you learn from it and you go-go-go.
In other words, human capital.
Most of the entrepreneurs I meet are not going to be homeless if things don't work out. They'll be employed.
Forgive me for asking, but (if it's acceptable to reduce it to that) isn't joining the army or something gets one covered? The army service would come with the added bonus of not letting you go soft in perseverance and risk taking areas.

…except it is. Health insurance is available on a sliding scale based on income and essentially free for most low income people.
I don’t think my older (step)son has had insurance since he got off our plan at 26 over two years ago.

That level of success requires either just pure psychopathic drive or some kind of deep anger that forces you to keep proving yourself again and again.
Beyond the lack of safety nets, etc., we just have a culture in the USA where you continually have to compete to prove your value as an individual.
There was some story I read where Farmers wanted to get immigrant laborers to work longer hours, so they offered a temporarily increased hourly rate. Like for the next month we pay $5/hr instead of just $3. The thought was workers would work like mad to hoard as much of the increased rate as they could. The opposite happened, they started working less because they just wanted $X/month and then to relax the rest of the time. That always stood out to me as a stark example that our American psychology is not at all universal, and is kind of perverted in certain lights.
It has one of the weakest social security systems. Not even proper healthcare is guaranteed. Yet it out innovates all of Europe, Canada, Australia, other places that have incredible social "safety nets".
I agree with the other commenter: safety nets and multiple tries are always good to have, but persistence and grit are even more important, and these come more from necessity.
