just finished; something just occurred
Says that an action was completed very recently, 'just did'.
たばかり expresses that something happened only a short while ago. Unlike ところ (which focuses on the immediate moment of completion), たばかり emphasizes that a certain amount of time has passed since the event, but it feels very recent. You often use it to explain why you are in a current state or why you cannot do something now. For example, if you just ate, you might say 食べたばかりです to mean 'I just ate (so I'm full / don't need more).'
This pattern can be used with any verb, but with state changes or achievements it sounds very natural. It is common in spoken Japanese and also appears in writing. Because it conveys a personal sense of recency, it often pairs with expressions like 〜ので (because) or 〜けど (but) to give a reason. Note that you cannot use it with adjectives or nouns; only with verbs in the past tense.
