I think so.
The ones I have been on usually have one or two bombs in place, so it doesn't give a great indication of how packed they were.
If I'm reading the chart correctly, there are 4 stations on each of the inner racks, and 2 stations on the outer racks that would take the 500lb bombs.
I don't know if those 12 racks are the only ones that could take the 500lb bomb, or whether other racks could be used when using a mixed load.
There are also 8 racks listed for the 1,600lb bomb, which would give a 12,800lb maximum internal load.
