有把握 is a separable verb-object phrase (离合词) meaning 'to be confident of success or a certain outcome'. The core is 把握 ('grasp' → 'confidence'). You can insert adverbs, measure words, or degree phrases between 有 and 把握 to fine-tune the certainty — e.g., 有一点把握 ('a little confident'), 有多大把握 ('how confident'), 很有把握 ('very confident'). The object you're confident about is introduced by 对 before the phrase: 对这个计划有把握 ('be confident about this plan').
