It can indicate a situation where you don't have enough money to access a certain type of opportunity, but it can also indicate a more subtle obstacle such as a sense of lack of confidence in your own abilities or in the abilities of others. In this case, you may feel stuck because of your fears and doubts about your ability to handle the situation.
