You might not like the answer. It depends on what type of show the audition is for and how good your agent is. For starters, if you are talking about Hollywood, it is incredibly competitive. There are so many people trying to make it. Working with an agent could potentially unlock opportunities, but even then 9 times out of 10 it doesn't pan out... The next option is Television, which is still very competitive. Some shows will cast repeatedly for roles that appear once in a series for just a few minutes, but that isn't steady work and it's practically impossible to line up enough of those to actually make a living just doing bit parts in TV shows. Then there's theater, where pay is terrible, but where there are more smaller parts that can be rewarding. The roles come in multi-month runs, so you have to string together a few of them each year in order to stay busy with your acting. It is hard to generalize how competitive all of this is because there are so many variants and local differences. What might feel competitive in San Francisco might not be considered competitive in New York. To give you an idea, early in your career you can easily go through dozens if not a hundred auditions before finding roles. For film you might not ever get the right role. Over time, you can develop a reputation, but it takes a long time and you need a lot of talent.
