Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Americans pronounce statue as STA-choo (/ˈstætʃu/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He carved a beautiful statue out of a single block of marble".
Record yourself saying "statue" and play it back. The mic stays on your device — nothing's uploaded.

Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Touch the tip or front edge of your tongue to the roof of your mouth just behind your teeth. Keep your jaw relaxed. Stop the air, then release with a puff.

Drop the jaw noticeably. Keep the body of the tongue low and forward, and don't let the back of the tongue raise toward the soft palate. Pull the lip corners back slightly, almost a starting smile.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch STA — keep everything else short and quick.
