Even if the receiver knows every sequence code for letters and symbols by head, how does he know where one letter starts and ends and how does he prevent overlap of 2 letter codes getting mixed up ?

Although we commonly say Morse is composed of dits and dahs, there’s a third element that’s just as important: space, or silence. There’s obviously a very short space between the dits and dahs of a letter, or it would be just one continuous tone. Then there’s a longer space between one letter and the next, and a yet longer space between the end of one word and the start of the next.
Ideally, the spaces within a letter are one dit-time, between letters are 3 dit-times (= one dah-time), and between words are 7 dit-times (= the time to send two dahs, including the space between them). Often senders will exaggerate the spaces to make copying easier, but some senders seem to shorten the spaces in a quest for speed, and it does make them hard to copy.
