No there's a 1 or 2 unit difference from where the player is in relation to the ground (not sure if speedshots happen at 0 or 1 unit over the ground, bounces are at 2 units), you go higher off a bounce than a speedshot, and you can speedshot from any height (there is probably a max) and bounce heights need to be very specific/lucky.
Both are 1 tick interactions with the ground where your velocity is temporarily set to 0 on your client but there is a slight difference.
Also I think (and have done no testing) that you can bounce at 0.X unit intervals as well but no one has bothered to measure them out because 1 unit is good enough and no one cares that much
