No, it simply means the vehicle manufacturer was too cheap to design adjustable suspension components when it engineered your car. When a car maker designs a car, engineers and accountants scrutinize each and every component to figure out how they can reduce manufacturing and assembly costs. If a few cents can be saved by leaving out an adjustable camber bolt, caster shim or whatever, they'll do it. They may have great faith in their own ability to build a vehicle that never needs to be aligned or fixed, but we all know from experience that such notions are untrue. So even though a suspension is nonadjustable and shouldn't require any corrections, that doesn't necessarily make it so. Even brand new vehicles can roll off the assembly line with wheels that don't meet their own alignment criteria.
Fortunately, the aftermarket has come up with ways to correct the "mistakes" of the vehicle manufacturers. If the car maker doesn't include provisions for adjusting the suspension, it creates an opportunity for some aftermarket part's supplier to come up with means of making such adjustments possible. These include offset bushings, shims, wedges and other alignment aids. So even though your suspension may have few if any adjustments for things like camber, caster and rear toe (front toe is adjustable on all cars and trucks), there are probably aftermarket alignment aids that allow at least some limited corrections to be made on nonadjustable suspensions.
