저 means I in a humble/polite way.
는 is the topic marker, so 저는 means something like as for me or I, personally.
In this sentence, 저는 sets up the speaker as the topic:
- 저는 평생 다른 사람을 돕고 싶어요.
In natural Korean, 저는 is often omitted if it is already clear who is speaking:
- 평생 다른 사람을 돕고 싶어요.
That sounds very natural too.
Both can mean I, but they do different jobs.
- 저는 = topic marker
- 제가 = subject marker
With 저는, the sentence feels like a general statement about yourself or your values:
- 저는 평생 다른 사람을 돕고 싶어요.
As for me, I want to help others for life.
With 제가, there is usually more emphasis on I as the person doing it, often in contrast to someone else or as new information:
- 제가 평생 다른 사람을 돕고 싶어요.
That version is possible, but in most normal contexts 저는 sounds more natural for this kind of personal goal statement.
