David Bradley does not count because Richard Hurndall does not count. Both of them are replacements for William Hartnell; it's not like they were formally cast to play the character as a new face, they are supposed to representing an old face. The only actors who count are the ones who have starred in the show as the main character in the numbered forms, the original twelve actors, as well as John Hurt from his face in the 2013 50th anniversary special. Now whether you want to count a fourteenth actor, Jodie Whittaker, who has not played the character on screen yet, is up to you, but other than that only the twelve main actors+John Hurt count, because these are the thirteen actors who have played distinct identities of the Doctor in the show.

TL;DR It does not count.
