This is very true. I work for a big bank and purposely overestimate any work because: 1) the veto culture; and 2) it allows me time to do work not counted in the "sprint". The actual amount of development I do is between 20-30%. The rest is taken up by "agile ceremonies" and convincing multiple layers of veto holders not to veto. Often times I'll spend 2-3 days developing a prototype and then 2-3 months convincing people its a decent idea. (I put "sprint" and "agile ceremonies" in quotes because its waterfall presented as agile)
