Audit strategy= Engagement letter content?

Is the aforementioned sentence true?

Short answer - NO See page 47 of the notes - the engagement letter is the written contract between auditor and client - contents on page 48. Some contents of the engagement will be standardised (as for any legal document). The audit strategy is an internal document that will be unique to each audit client, setting out how the auditor's objective (i.e. to express an opinion on the financial statements) will be achieved.
