Yes.. all plants need water
Plants need water for photosynthesis.
Photosynthesis is what plants do to create their food, and water is critical to this process. Water enters a plant's stem and travels up to its leaves, which is where photosynthesis actually takes place.
All living things, in order to perform their bodily functions, need water. Plants specially need plenty of water for their metabolism to remain homeostatic plus carrying out photosynthesis.
Some plants, however, can survive with little to no water at all during a period of latent life or "dormancy", typically seen in seeds. Nonetheless, as soon as they resume normal biological processes and growth, they need water again.
Other plants, like cacti or succulents, carry out their lives with little but regular input of liquid water. As they also need a certain amount of water, they compensate the scarcity by reducing liquid waste to a minimum through different strategies (shorter leaves, waxy epidermis, etc.).
In the other hand, many plants have to get rid of water excess when water is abundant. In tropical rainforests, plants produce most of the air humidity through "evapotranspiration".
Extreme cases of water availability are found underwater. Aquatic flora deal with such conditions by lacking the hydrophobic cuticule most terrestrial plants require to survive fatal dehydration, thus allowing water to flow freely in and out of its cells.
TL;DR: Yes.

All plants need water
- They need water for photosynthesis.
Photosynthesis is what plants do to create their food, and water is critical to this process.
However some plants need little water like the cactus. However, don't mistake them as not needing water. They need only little water as they are adapted to desserts where water is scarce.
In conclusion,
All plants need water. But, they need different amounts of water to survive.
