In order to grow bamboo to its full height, you have to give it plenty of room. In a pot, it won't achieve its full potential height it would grow to in open ground. The other factor is water. As mdw84 above said, they water their bamboo in a huge pot nearly every other day. If you don't or can't to that and/or your pot is small, then that will impact on its height. Bamboos in open ground that clump rather than run are generally well behaved, but even they might need containing with a barrier if you want to stop it from spreading too far or outside the boundary of where you want it to go. Digging it up and splitting it might sound relatively easy, but I've seen examples of people trying to split a bamboo in the ground and a pot, and people have snapped spades and have had to use an electric saw to get thru' the roots and rhizomes of a mature bamboo. Not for the faint hearted!
