there are two methyl groups in acetone and oni in acetaldehyde

correct! The most important factor for their stability order is Steric Hindrance due to large methyl groups. More the methyl groups, less the reactivity. So acetone has the least while formaldehyde is the most reactive.

If you are talking about nucleophilic substitution reactions then it's correct......But say for example haloform(\alpha substitution)reaction there even ethanol is more reactive than formaldehyde(which doesn't undergo haloform reaction at all)
