The title is Mana Seed Tileset Collection. It contains all of the Mana Seed tilesets. A "tileset" is a collection of tiles used to form a background environment. There is a very explicit list of all the tilesets contained in this collection, along with helpful links:
The title and text are in agreement, and there are no confusing implications. The text you quoted says that I might prepare OTHER assets (like my monsters) for Unity, if this pack proves popular. It doesn't say anything anywhere about monsters being in THIS pack.
And to clarify further, there will never be monsters in this pack. Because this is a tileset collection. If I ever prepare my monsters for Unity, they will be in a separate pack.
If you want the full Mana Seed collection, that includes all assets found here on itchio (even monsters). You can find that option in my Ko-fi shop:

But I urge you to also read that page before buying.
Thank you! 🙏🏽
