The way bamboo grows makes it difficult to create good bonsai. First of all, they are the fastest growing plant in the world, which
makes all types hard to control in a container.
One of the potential problems in styling a bonsai is these plants don't have, what we usually think of as real branches. In addition, the rhizome root system is unique.
"A rhizome is a modified subterranean stem of a plant that is usually found underground, often sending out roots and shoots from its nodes." Source -Wikipedia
Despite the number of species, there are basically two types of bamboo, one grows in "clumps" and the other is a "runner."
When buying these plants, especially when planting them in the ground, always ask which type it is. "Running" bamboo is invasive!
Individual stalks only live for a limited number of years, depending on the species. In a landscape or garden, these dead stalks are cut down and they are soon replaced by new ones.
For this reason, bamboo is most often used in groupings or forests. This way a stalk can often be removed without destroying the composition. Because of the way the rhizomes grow sideways, sometimes this plant is perfect for shallow containers.
This shallow pot known as a suiban ... has no holes in it. (This type of container is often used in Ikebana, the Japanese art of flower arranging, rarely for bonsai.)
The substantial root system of bamboo is fine with this ability to hold water. It will help keep it moist in a small amount of soil. Look closely and you will see the beautiful carved "feet" raising the pot off the ground.
"Lucky Bamboo" is Dracaena sanderiana. It is not in the bambusa family.
It is a plant that grows easily indoors, and has become very popular. Sometimes they are sold growing in water. They will live for a limited amount of time this way. However, you will have better success when planted in soil.
It can be attractive, and sometimes even fun, but "Lucky Bamboo" is not bonsai, nor bamboo.

Being in a bonsai pot, does not make it a bonsai.
Some consider the segmented stems of older Nandina plants to resemble bamboo, it is not.
It is occasionally used as an accent, or
companion plant, when displayed in bonsai exhibits.
