No. Whatever statistic describing position players as more value than pitchers is not measuring value. Let's start with percent of each action a player is involved. Pitchers are involved in every play while position players are not.
One model is that runs scored and runs allowed have equal value, so half the value of a win is spread among the offense and half the defense. Of the defensive value, on average there are 7 outs due almost exclusively to the pitcher (Ks, but framing has something to do with it) and 20 due to defense. Pure defensive independent pitching theory says pitchers have no control over the out / safe outcome of a ball in play. Pure DIPs is wrong in that pitchers have some influence over batted ball outcomes, but it is not so far off that it is more than fine tuning. So, while it is true that every play starts with the pitcher throwing the ball, that really has next to nothing to do with value. Positional players pick up most of that 50% of the value assigned to offense, and a decent amount of the defensive value of outs that aren't Ks.
