Bitcoin blocks are mined every 10 minutes on average. No matter how long it's been since the last block, the chance of finding the next block remains the same.* You'll occasionally notice 1+ hour elapse without a new block being mined.

*Economically speaking, a long interblock time would lead to a higher fee reward for the next block, which would eventually lead to more hashrate being produced. But at this stage of mining maturity, you can just consider it random.
