All biomes in any given World?

depends on the seed you used. If you are not lucky, try another direction or a new seed

i mean usually a seed contains all biomes. Just where you find which depends on your seed.

yep currently biomes spawn completely at random based on your world seed, I would recommend using F2 (fly mode) to find the biome you want faster, then you can land and continue playing in survival mode if you so wish

As @Avanar said every world should in theory have at least one of each biome but some may appear less than others

red said that there may be a way to control the starting biomes (i.e. around the spawn point) at least in the future but it is not certain yet, have a look here: Customisable or better Predefined World Generation
