That's off by an order of magnitude. It's not 7%, it's 77%

But, only a small percentage of global soy is used for these products. More than three-quarters (77%) of soy is used as feed for livestock.

When we look at the most common extraction method for soybean oil (using hexane solvents), soybean meal for animal feed (not oil) is the driver of demand

However, soybean meal is the main driving force for soybean oil production due to its significant amount of productivity and revenues

[...]

soybean meal and hulls contribute to over 60% of total revenues, with meal taking the largest portion of over 59% of total revenue

This is even more true of other methods like expelling which is still somewhat commonly used

Moreover, soybean meal is the driving force for the whole process [expelling oil from soy] because it provides over 70% of the total revenue for soy processing by expelling
