Current Target Wall Mounts are crap. Use one at your own risk. Seek out an original like this one that just sold:

and compare them, even visually, online.
I use one like the one linked to above. Secured into studs there will be no problem with the frame with a 50 or even 75 pound table.
The MDF shelf (which should be replaced anyway) will flex and sag a bit with a heavy table. A 3/4" or 1" piece of baltic birch should fix that and be relatively inexpensive.
Ideally, a constrained layer shelf can be made using a couple of pieces of baltic birch with a piece of 1/8" neoprene sheeting between them without breaking the bank.
I use extruded acrylic for the top layer of my shelf and found it to be worthwhile but it's pricey when compared to the baltic birch.
