She's female. T albos are sexually dimorphic and hard to mistake ventrally. You look at a few examples in this space and you'll see that females have the lighter colored hairs running horizontally above the epigastric furrow. Males instead are dark throughout with an even darker, denser spot or arch above the furrow. That dark patch are the epiandrous fusillae for which this forum is named.

Very few species of tarantulas are sexually dimorphic, and T. albopilosus is not considered among them. Males and females look identical up to maturity - ventrals do not count as that's a difference in sex organs (epiandrous fusillae, epigastric furrow, etc) whereas dimorphism is a differences outside of those; coloration, patterning, and body build to name a few. Pelinobius muticus would be a good example of the last.
Nitpicking about semantics aside, I do concur that this T does appear to be female based on the ventral view, between the "lippy" appearance of the furrow and the lack of any glaringly obvious epiandrous fusillae. Always confirm with a molt when you can, as it's really the only surefire way to be certain without a shadow of a doubt. Aside from when a male matures and actually does look notably different from the female, and nobody likes finding out that way.
