Not exactly, the math is involved in it. Basically the mining is based on probability. We have a number called target that is the highest value a block header hash can have. The miners construct the header and compute its hash. Then they continue making small changes in that block to compute the hash again and again until the result is smaller than or equal to that target.
This target is adjusted every 2016 blocks in a way that the time it takes to mine the next 2016 blocks be 2 weeks.
