Unfortunately, with that kind of rifle, supplied scope, and ammo coupled with a beginner shooter's ability, yes it is.
Now for the good news. These bargain guns can shoot much better than that, but there are some things to do first.
One: The pellet head must fit the bore. This is the most critical for accuracy. Now you didn't say if you got a .177 or .22. However, both calibers have variable bore sizes, with the .22 more-so since the Germans and English established two different standards for .22.
To check if the pellet has a good fit, you need to push the pellet down the bore but stop before it gets to the choke, and then push it back out to the breach. Most airguns are choked at the muzzle which generally helps with ill fitting pellets, but only to a point. Check that the head has light engraving of rifling and that the skirt is well rifled. Pellets whose heads do not engrave at all, or are heavily engraved will not shoot well. Better quality pellets have more uniform head sizes than the things like the Gamo pellets.
H&N pellets are made with more variety of head sizes than other manufacturers so this may be what you may wind up ordering. Their "Field Target Trophy" pellets are among the best, with JSB Exacts often being a bit better though not offered in as many head sizes. Other good brands are Crosman Premiers, FX, and Beeman.
Two: The bargain scopes that are supplied with these guns are pretty much junk. Even though the spring gun recoil won't technically break them, they won't hold zero well even on a mild PCP. Every once in a while, such a scope will be surprisingly consistent, but it is more an oddity than anything else. I suggest replacing the scope with a much better airgun scope. The Hawke Airmax line are among the better, and more affordable though some examples may exhibit problems as with any products from China. The scope rings also must have a pin or screw that fits into the recoil recess (usually a blind hole) in the dovetail. Without this retaining device, the rings will eventually slip.
Don't discount using irons either. Young eyes can do quite well with irons. A Williams aperture sight on the rear will work better than many scopes under $200. Another benefit of irons is that it somewhat discourages taking shots that one shouldn't. But, this is no guarantee, for my brother and I at that age would pop shots off at pest critters 100 yards and more with our Sheridan Blue Streak.
Three: Shooter's technique and consistency is a big one with these guns, too. Spring airguns are notoriously difficult to shoot well from a bench. However, once mastered those skills will improve general rifle benchrest shooting. It is actually easier to shoot a spring airgun well if one uses the artillery hold. The trick is to hold the rifle's forend at the ideal point and let the butt end float as best as possible. What that point is varies with the rifle and shooter. This point is even more critical with benchrest. (I know too well about this for I am the second place shooter at last year's 2019 Extreme Benchrest Spring Gun Class---far behind the first place winner. I'm still learning.)
For an example on how much hold can play my RWS 34 (my first "good" spring gun and airgun in general) will print shots in two different points 3" apart at 10 yards depending if I hold it tight to my shoulder (consistently) or use the artillery hold. The artillery hold produces only slightly better groups at this distance but either group will be shooting 9s at the 10 meter airgun target. Note, the ten ring on this target is the size of a regular printed period. Most of the change is in the vertical but there is a horizontal component as well. This is a lot of what I see in your ~15 meter target you posted.
