What does "when an effect places the top card of one of your Digimon in a Digimon's digivolution cards" in this card's ＜Your Turn＞ effect mean, exactly?

You place the top card of one of your Digimon in the digivolution cards of that Digimon or another of your Digimon. This doesn't include when the top card becomes a digivolution card through digivolution.

I used this card's ＜Start Opp Turn＞ effect to play and DNA digivolve a Digimon. In such cases, does the played Digimon's ＜On Play＞ effect activate?

No, it doesn’t. The ＜On Play＞ effect will trigger, but it can't activate because the Digimon becomes a digivolution card through DNA digivolution before the effect activates.
