More experienced freelancers yes, but someone starting out, or with a small clientele base, a lot of time don't take things like that into account, especially if they are trying to growing their brand and business. Clarity into revenue matters and can be overlooked sometimes in the pursuit of appealing to a client.
Usually, if you are just starting out you will tend to work for bad clients because good clients are those with regular work that pays well who value stable business relationships.
Bad clients are those (in order) who don't value stable relationships, don't pay well, and who don't have regular work. The best likely good client for a new contractor/freelancer/consultant is someone you can grow your business alongside their growth...and that's a long term relationship.
If you are worrying about your hourly rate, you probably won't make it because relationships are what matters. If you don't have enough resources to build relationships over time, you probably won't make it.
Your job is solving client problems (other than paying you).
