The way physicists understand this is that the curved space-time view of gravity is an approximation that is only valid when you have a lot of gravitons. In that situation you do not see individual gravitons but only the aggregate effect of the ‘sea’ of gravitons you are in. This is similar to e.g. fluid dynamics, which is only valid at scales much larger than the atomic scale. But if you look close enough, you will see effects that are not consistent with viewing a fluid as a continuum of matter (e.g. minute specks of dust moving randomly because they are hit by individual atoms).
