During a war, one may expect tank counts for both sides to go decrease (i.e. as they engage in combat and are destroyed).
MSNBC reports Forbes stating:
The Ukrainian army has more tanks now than when the war began
with the rationale being:
because it keeps capturing them from Russia
Imperfect data
Combat statistics aren't always accurate. For example, statistics reported from the Land forces of the Armed Forces of Ukraine include the note:
Підрахунок ускладнюється високою інтенсивністю бойових дій.
which translates to
The calculation is complicated by the high intensity of hostilities.
Some data collectors have even opted only to report on statistics backed by photographic evidence. For example Oryx only accounts for destroyed/damaged/captured equipment where photographic evidence is available.
Is it true?
From what is known publicly, is it true (or likely true) that Ukraine has more tanks now - 31 days into the Russian invasion of Ukraine - than it had on 24 February 2022 when the war began?
