Python telegram bot, how to store and show users data for each users? – Telegram API

Hello I am new one for python and telegram api so i have some questions. I am creating telegram bot(python telegram api) with users profile. I have created database(mysql.connector) and store there all users info after registration. Also i have created user class. When user types /start i am checking if it exists, if it is, i am filling this class. Then i use this class to show some profile information(photo, name, age, etc.) if users click on button(my profile). So the problem is when i have 2-users at the same time. First typed "/start" and logged in, wanna watch self profile, everything fine. But when second user do the same, i got that the first users when clicked on (my profile), he or she got the last one profile who typed "/start" loaded for both users. How to fix this? Solution to check and load data all the time sounds not good, i’d like to do smth with "class Users", but i don’t know to make it uniq for each users session. Any solutions? If it’s needed i can give more code, just ask.

class Users:
def __init__(self, id=0, name='', age=0, gender='', balance=0, telegram_id=0, photo='', sallarytext=0, sallaryvideo=0, videocall=0):
    self.id = id
    self.name = name
    self.age = age
    self.gender = gender
    self.balance = balance
    self.telegram_id = telegram_id
    self.photo = photo
    self.sallarytext = sallarytext
    self.sallaryvideo = sallaryvideo
    self.videocall = videocall


user = Users()


def check_auth(connection, telegram_id):
cursor = connection.cursor()
result = None
try:
    cursor.execute("SELECT * FROM users WHERE telegram_id = '%s'" % telegram_id)
    result = cursor.fetchall()
    data = []
    if result:
        for row in result:
            user.id = row[0]
            user.name = row[1]
            user.age = row[2]
            user.gender = row[3]
            user.telegram_id = row[4]
            user.balance = row[5]
            data = [user.name]
        if user.gender == 'Female':
            cursor.execute("SELECT * FROM photos WHERE users_id = '%s'" % user.id)
            result2 = cursor.fetchall()
            for row in result2:
                user.photo = row[1]
                user.sallarytext = row[2]
                user.sallaryvideo = row[3]
                user.videocall = row[4]
        return data
except Error as e:
    print(f"The error '{e}' occurred")
