No, it isn't. Those types of deals never come close to a standard game's budget, and it usually isn't being directly headed towards that specific project.
Nice try, though. As I said, you're not fully funding a project you're not publishing.
It isn't a try, I'm a gamedev with two decades of working experience who knows people from many dev studios and publishers, explaining you the factual difference between funding a project and publishing it, because you have no fucking idea what are you talking about.
Funding a game and publishing a game are two totally different and unrelated things.
To fund a game is to pay totally (or partially) the budget of the game. In some cases the publisher funds totally or partially the game, but often in the case of indies they don't and the budgets are self funded with a mixture of sources, typically self funded by the gamedev studio with personal savings or previous sales, or via friends, families and foes, government grants, incubators/accelerators, business angels, bank loans, investors, crowdfunding, maybe some deal with a platform holder to get a some kind exclusivity or marketing deal, Epic Games mega grant, etc.
In most cases those who fund totally or partially a game don't publish the game. They are just supporting the studio, or invested on it to get a part of the company, or a percentage of the sales of the game, or paid them something as part of a deal.
Publishing the game means to sell it to the audience and manage the related paperwork of age rating management, certification management, uploading it to digital stores and filling its metadata and paperwork, payment/refunds/chargebacks management, and in case of physical editions to make the packaging, stockage of physical copies, selling it to retailers and shipping it. Many small publishers of indies only do this: the dev studio funds and develops the game, and the publisher sells it.
Optionally, depending on the publisher or the specific case of the game, the publisher can also fund totally or partially the game, or do themselves part of the development, manage and fund outsourcing teams, offer tech support, offer devkits and testkids, motion capture or dubbing, localization, player research/focus testing/playtesting, testing, internal mock reviews, marketing, PR, community management, community support, IP management, legal support, etc.
The deal to share the revenue generated by the game will depend of whatever they sign and whatever services the publisher offers to the dev, but often the 100% goes to the publisher until the publisher recoups whatever they invested in the game, and after that they typically split 70%-30%, or in some cases 50-50%. In some of the cases of the 50%-50% split starts since the beggining, without recouping, and often is in the indie publishers who only publish and don't do anything else.
As an example, Sony publishes Stellar Blade worldwide in both platforms but they only partially funded the game, and Shift Up funded the rest via different sources. In addition to publishing and partial funding, Sony provided development support via internal and external outsourcing teams plus made marketing, PR and a ton of other things you can see in the game credits.
Most <Region> Hero Project games are not published by SIE. They help studios find publishers, or help them self publish. If they're announcing further support(dev/funds), they're likely publishing it.
When Sony publicly announces a strategic partnership with a game under the China Hero Project, it often signals intent to publish or co-publish, not just support.
In the Hero Project initiative Sony provides small and often new dev teams of these regions marketing & PR support, mentorship in the different areas related to gamedev, tech support and at least in some cases (as for these two announced) Sony funds partially or totally the development. And then these studios selfpublish or find a publisher.
As I remember, out of all the ones already released or announced (a few dozen titles), only Lost Soul Aside and Convallaria have been announced that will be published by Sony.
See in the previous part of this post the difference between funding and publishing a game.
