Because there is always some variance. You’re quite unlikely to get *exactly* 50 heads and 50 tails (~7%), but you’re very likely to get *around* 50 heads and 50 tails. The more you throw your coin the “error” grows slower than the overall ratio, so even if you’re not exactly on the nose with 50:50 the overall ratio between heads and tails will converge closer and closer to 50:50
