not necessarily. you can't look just purely at HT angle.
'Race' bikes will tend to have lower stack than 'endurance' bikes. lower stack ( usually corresponding to lower HT height) allows you to go really low and be in a more aggressive position. they will also usually tend to have shorter wheelbase and shorter trail so they 'handle' faster. Race bikes will also aim all out for lightweight/stiffness/aero with no compromises for comfort. Endurance bikes will usually have some sort of concession for comfort- e.g. specialized roubaix with zertz, Trek Domane, bianchi infinito CV with countervail, and don't necessarily emphasize lightweight, aero, etc.
the whole 'endurance' and 'race' bike thing is a misnomer, really. The differences are small. Cancellara races his domane all year round. Tom Boonen uses the venge, an aero race bike, on the cobbles. Robbie Hunter used the Bianchi Infinito as a sprinter bike in the 09 Giro and even podiumed on it. I myself race a Bianchi Infinito since it fits my awkward body well. get a good fitter to tell you what geometry will fit you and what your numbers are. No point buying a race bike and having to use 5cm of spacers.
