Statistics of real lotteries:

This is a table of values that appear in each digit of winning numbers in all drawings of the Summer Jumbo lottery (historical of draws). Winning numbers are typically distributed across different groups and series.
Some groups tend to appear more frequently in historical draws.
You can use this assessment to place bets with numbers that do not appear in the history.

You can reach the following conclusions:

Consecutive number combinations (e.g., 123456-123457) are extremely rare, with only adjacent prizes showing ±1 differences.

No dominant number range (like 80,000-99,999) exists, but digits in each position tend to be evenly distributed, with slight historical variations.

The ticket group (1-200) is significantly easier to predict than the exact 6-digit number, with a 5,000 times higher probability.

Specific numbers within a group are the hardest to predict due to high randomness, with 1 million possible combinations.

These are the highest prizes achieved in simulations for the 1st prize or adjacent prizes.
