you should be able to trust that the numbers are correct or at least what Hasbro believes they are
spin does not mean that they have to hide failing sales numbers and D&D is close to being shut down due to lack of sales, it simply means they portray it in the best light possible
WotC is a significant part of Hasbro, esp. when you focus on the profit side of things rather than revenue, and while D&D is nowhere near as big as MtG, it is pretty up there in terms of products Hasbro has, probably their second or thirdmost profitable product after MtG…
