Build a short fictional sequence
Suppose three batters complete turns lasting one, eight and four pitches. That is thirteen pitches across three completed plate appearances. Dividing 13 by 3 gives about 4.33 pitches per completed turn in this simplified sequence. It does not mean the pitcher faced thirteen batters.
The eight-pitch turn could contain foul balls that leave a two-strike count unchanged. Its length does not imply that eight outs, eight at-bats or eight runs occurred. A pitch-by-pitch replay and a box score can therefore summarize the same passage with very different numbers.
Do not substitute at-bats for plate appearances
A completed turn ending in a walk is a plate appearance but is not an official at-bat. Suppose those three batters produce an out, a walk and a single. The simplified batting record contains three plate appearances but two at-bats. The thirteen-pitch total remains a separate workload figure.
This matters when interpreting a batting average or a graphic describing a player as one-for-two. That phrase can coexist with three completed turns if another turn was a walk. It does not necessarily mean a broadcast skipped a plate appearance.
Match your evidence to the question
To understand how hard a pitcher worked, use pitch counts and the sequence of events. To calculate batting average, use hits and official at-bats. To count completed batting opportunities, use plate appearances. None of those questions is answered by silently replacing its denominator with another one.
There are also situations in which a batter is at the plate when the inning ends through a runner being put out, leaving that batter without a completed plate appearance at that moment. For a detailed reconstruction, consult the official play-by-play rather than counting every camera shot of a batter as a completed turn. Keep partial and completed sequences distinct. A clear viewing note names the batter, the outcome and the number of pitches, allowing another reader to understand both the result and the work required to obtain it.

No. The figures are invented to show the calculation.
