Why can't I forecast my sales pipeline accurately?

Managing the work in front of you and predicting where it lands are two different skills. You've learned the first. The second feels like it should follow, but it doesn't, because a forecast asks you to be honest about things you can't fully control. That discomfort is not a sign you're bad at it. Most forecasts go wrong because we trust the story a deal tells us instead of the evidence. A hopeful client, a warm call, a promise to sign next week. Feelings creep into the numbers. The fix is to judge each deal by what has actually happened, not what you wish would happen. Ask of every deal: what has the buyer done, not said, to move this forward? Start with one small habit. Once a week, mark each open deal by its real stage and note the last concrete action the buyer took. Over a few months you'll see your own patterns, where you tend to be too hopeful. Accuracy comes from that honesty repeated, not from a better spreadsheet.
