No, not all elements are abbreviated by one or two letters. While most elements have one- or two-letter symbols, there are exceptions for certain isotopes or compounds, which may have longer designations. However, in the context of the Periodic Table, all elements themselves are represented by one or two-letter symbols.
The first word (the genus) may be abbreviated.

There are 13 elements with one-letter symbols: B (boron), C (carbon), F (fluorine), H (hydrogen), I (iodine), K (potassium), N (nitrogen), O (oxygen), P (phosphorus), S (sulfur), U (uranium), V (vanadium) and Y (yttrium). That single letter must always be capitalized.That the names have only one letter is not relevant to their chemical properties; it just means that the single letter seemed the most appropriate way of abbreviating them at the time of discovery/categorization.You'll notice that most of those elements' one-letter abbreviations are just the first letter of the elements name. The conspicuous exception is potassium, abbreviated K. It could probably have been abbreviated as Po, Pt or Pa -- polonium, platinum and protactinium were discovered later -- but K was chosen nonetheless. This is derived from the invented Neo-Latin word Kalium, derived from Germanic languages with similar words meaning potash (potash being the source of both the metal potassium and the English name for it).
The Tyrannosaurus Rex is usually abbreviated T-Rex.
Some elements have weird abbreviations because they are derived from their Latin or Greek names. The abbreviations are often based on the first letter or first two letters of the element's name in a different language. This can lead to unconventional abbreviations that may not make immediate sense in English.
