During preamble transmission, how devices choose the frequency band in PRACH for preamble transmission?

If they choose the frequency in PRACH randomly, then there can be the chance of sub-channel(frequency band to send preamble) collision. If above statement is true then how many devices can send the preamble at a random access time slot?
