An RCD will not prevent you from receiving a shock.
An RCD does not reduce the shock current, but will limit the duration of that shock current to a time based on the residual current detected, as shown in Table 3A of BS 7671.
An RCD is not guaranteed to protect you against physiological effects, but on the statistical balance it will.
The inventor of the RCD actually did expose themselves to shock to test out their theories !
Under some conditions (contact area, what you have on your feet, how wet you are and what's in that water), the shock may be more severe.
It's possible to touch a conductor protected by an RCD, and receive quite a nasty perceptive shock, without the RCD operating. Most electricians will know about this, and be fully aware that the greater risk of exposure to shock is physical injury from secondary effects.
I'm sure everyone that contributes to this forum is aware of these limitations ... and of course no-one would choose to touch hazardous live conductors.
IEC 61140, product standards, and BS 7671, do not guarantee 100 % protection from electric shock, but are intended to meet the essential requirements of the LVD, or Electrical Equipment (Safety) Regulations, along with the Electricity at Work Regulations - many of the requirements are "SFARP".
